A table is rectangular and its length is twice its width. Find the dimensions of the table if it occupies 72 ft2 of floor space.

Question

 What is the width and length of table

Answer 1

L = 2W

 

A = 72 ft^2

 

A = LW = (2W)W = 2W^2 = 72 ft^2

 

W = √(72/2) ft = 6 ft

 

L = 2W = 2(6) ft = 12 ft
