The area of that rectangle is 150 square inches. The result is obtained by using the formula of the perimeter dan area of pictures.
<h3>How to find the perimeter and area of a rectangle?</h3>
A rectangle is a two dimensional shape consisting of four joints. It has also four angle points.
The perimeter and area of a rectangle can be expressed as follows.
P = 2 (w + l)
A = w × l
Where
- P = perimeter of a rectangle
- A = area of a rectangle
- w = width of a rectangle
- l = length of a rectangle
The perimeter of a rectangle is 800 inches. The width of the rectangle is 60% of its length.
From that information, we have:
- P = 800 inches
- w = 60% × l = 0.6l
P = 2(w + l)
800 = 2(0.6l + l)
400 = 1.6l
l = 400/1.6
l = 250 inches
The area of the rectangle is
A = w × l
A = 0.6 l × l
A = 0.6 l²
A = 0.6 × 250
A = 150 square inches
Hence, the area of that rectangle is 150 square inches.
