Question

The width of a rectangle is 8 inches. The length is 4 times its width.What is the area of the rectangle?

Answer 1

`A=256\ in^2`

Explanation:

Area of a Rectangle

A rectangle is a four-sided polygon with four internal right angles. The sides are called width (w) and length (h). Two important measures about the rectangle are the area (A) and the perimeter (P):

`A=w.h`

P=Sum of the four sides

`P=2(w+h)`

We know the length is 4 times the width and the width is 8 inches, thus

`w=8\ in`

`l=4\ in\cdot 8\ in=32\ in^2`

Thus, the area of the rectangle is

`A=8\ in \cdot 32 \ in=256\ in^2`

`\boxed{A=256\ in^2}`
