Question

The perimeter of a rectangle is 96 inches. The length of the rectangle is three times its width. Find the dimensions of the rectangle.

Answer 1

Hey there!!

Perimeter of a rectangle =2 ( length + width )

Let's take the measure of the width as ' x '

Then, the length would be ' 3x '

Hence,

... 2 ( x + 3x ) = 96

... 2 ( 4x ) = 96

... 8x = 96

... x = 96 / 8

... x = 12

Width = 12 inches

And, length would be 36 inches.

Hope my answer helps!!
