what is the formula for area of a square and rectangle
To find the area of a rectangle, multiply the length by the width. The formula is: , where is the area, is the length, is the width, and Â· means multiply. A square is a rectangle with 4 equal sides.To find the area of a square, multiply the length of one side by itself. The formula is: or, where A is the area, s is the length of a side, and Â· means multiply.Let's look at some examples of finding the area of rectangles.iven the length and width of a rectangle, we can find the area. Given the area and one dimension of a rectangle, we can find the other dimension. The formula for area of a rectangle is: where is the length and is the width.
Units. Area is measured in square units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.(Square inches can also be written in2.) Be sure to use the same units for all measurements.nits. Area is measured in square units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor.
