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 To find the area of a square, multiply the length of one side by itself. 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.
