Perimeter and area of a rectangle if its length is 720 m and its width is 4/5 of its length.

Let’s find the width of the rectangle if it is known that the length of the rectangle is 720 m, and the width of the rectangle is 4/5 of its length:

720 x 4/5 = 576 m – the width of the rectangle.

Let’s find the perimeter of the rectangle if it is known that the perimeter is the sum of all sides of the rectangle, the length is 720 m, and its width is 576 m:

720 + 720 + 576 + 576 = 2592 m.

Let us find the area of a rectangle as the product of its length by its width, if it is known that the length of the rectangle is 720 m, and its width is 576 m:

720 x 576 = 414720 sq. m.
