Question

A.  3 feet

B.  6 feet 

C. 7 feet 

D.  12 feet

Answer 1

You cannot state definitively the width of a rectangle whose area is 36 sq ft unless you know the length!

 

The first rectangle could have width 1, length 36 & the second rectangle could have width 1, length 21.

But other answers are possible.
