Question

The perimeter of a rectangular tabletop is 384 cm. It's width is 3/5 of its length. Find the dimensions of the tabletop

Answer 1

Length: 120cm, Width: 72cm

Explanation:

Let x = length

Let 3x/5 = width

2x+2(3x/5)=384

2x+(6x/5)=384

16x/5=384

16x=1920

x=120cm

Substitute 120 for x in width

360/5 = width

width = 72cm
