Area of a rectangle formula1/4/2024 ![]() ![]() Why is the Area of a Rectangle Length Times Width? L 2 means to multiply the value of L by itself. Using the alternative form of the formula, we have Area = L 2. We simply multiply 6 by 6.Ħ cm × 6 cm = 36 cm 2 and so, the area of this square is 36 cm 2. The area of a square is found by Area = Side Length × Side Length. Here is an example of using the formula for the area of a square with a worded problem. This formula can be written more simply as Area = L 2, where L is the length of one side of the square. The formula for the area of a square is Area = Side Length × Side Length. However, the length and the width are both the same on a square, which makes it even easier to find the area. Multiplying the length by the width, the area is 3 m × 3m = 9 m 2.īecause a square is a type of rectangle, the formula for calculating the area of a square is the same as the formula for calculating the area of a rectangle. Here is a square with a side length of 3 m.Ī square is a special type of rectangle that has all of its sides the same length.īecause all of the sides of the square are 3 m long, the length and the width must both be 3 m long. For example, if a square has a side length of 3 m, then its area is 3 m × 3m = 9 m 2. To find the area of a square, multiply the length of one side by itself. In this worded problem, we just need to find the two numbers that show the length and width.Īrea = 7 × 5 = 35. The area is found by multiplying the length and the width. Here is a word problem for finding the area of a rectangle. The units for the area are cm 2 since we measured the sides in centimetres. ![]() Here is an example of using the formula to calculate the area of a rectangle.Ī = 9 × 4 = 36. This formula can be written as A = L × W or as A = LW. The formula for the area of a rectangle is Area = Length × Width. In this example, the length is 8 cm and the width is 5 cm.Ĩ × 5 = 40 and the units for the area of this rectangle are cm 2. The length of a rectangle is the longest side and the width is the shortest side. For example, for a rectangle of length 8 cm and width 5 cm, the area is 8 cm × 5 cm = 40 cm 2. The area of a rectangle paper of 45 square inches and a width of 5 inches.To find the area of a rectangle, multiply its length by its width. The area of a rectangle rug 28 square feet and a length of 7 feet. The area of a square is 25 square centimeters. ANSWER BOX: A = in 2Ī rectangular yard has a length of 12 meters and a width of 4 meters. 1.įind the area of a square with each side measuring 6 inches. This will help you practice finding the area of a rectangle. After you click ENTER, a message will appear in the RESULTS BOX to indicate whether your answer is correct or incorrect. Your answers should be given as whole numbers greater than zero. Click once in an ANSWER BOX and type in your answer then click ENTER. The formula for area of a rectangle is:Ī = L * W where L is the length and W is the width.Ī square is a rectangle with 4 equal sides The formula for area of a square is:ĭirections: Read each question below. Given the area and one dimension of a rectangle, we can find the other dimension. Given the length and width of a rectangle, we can find the area. Summary: The dimensions of a rectangle are length and width. So must equal 3 cm.Įxample 4: The area of a rectangle is 12 square inches and the width is 3 inches. Let's look at some examples in which we are given the area of the rectangle, and are asked to work backwards to find the missing dimension.Įxample 3: The area of a square is 9 square centimeters. In Examples 1 and 2, we found the area of a recentangle given the dimensions of the rectangle. Let's look at some examples of finding the area of rectangles.Įxample 1: Find the area of a square with each side measuring 2 inches.Įxample 2: What is the area of a rectangle that has a length of 8 centimeters and a width of 3 centimeters? Or where A is the area, s is the length of a side, and The formula is:Ī = L * W where A is the area, L is the length, W is the width, and * means multiply.Ī square is a rectangle with 4 equal sides. To find the area of a rectangle, multiply the length by the width. Area is measured in square units such as square inches, square feet or square meters. Area is 2-dimensional: it has a length and a width. Perimeter is 1-dimensional and is measured in linear units such as inches, feet or meters. To understand the difference between perimeter and area, think of perimeter as the length of fence needed to enclose the yard, whereas area is the space inside the yard. The area of a polygon is the number of square units inside the polygon. How To Find The Area of a Rectangle Using Area of Rectangle Formula.
