Question

A rectangle is three times as long as it is wide. It’s perimeter is 60 in. What are the rectangle’s dimensions?note:the perimeter is the sum of all four sides of a rectangle

Answer 1

width=7.5in, length=22.5in

Explanation:

let the width=x

then the length=3x

Perimeter of a rectangle=2l+2w

60in=2(3x)+2x

60in=6x+2x

60in=8x

x=60in/8=7.5in

Since x=width,width=7.5in and length=7.5in×3=22.5in
