The length of a rectangle is six times it's width if the area of the rectangle is 600in find its perimeter

Perimeter = 140 inches

Step-by-step explanation:

Area of recatngle = L*B = 600in

let the width be x

then the length will be 6x

A = 6x*x = 6x²=600

x²=600/6=100

x=10in

length = 6*10=60 in

Perimeter = 2 (L+B)

P=2 (60+10) = 2 (70) = 140inches
