Question

A pool is surrounded by a rectangular fence with a

perimeter of 72 yards. If the length of the fence is 3
times the width, what is the length of the fence, in yards?

Answer 1

width is 33

Explanation:

width (b) =?

length(l)=3

perimeter (p)=?

now,

perimeter = 2(l+b)

or,72= 2(3+ b)

or,72/2= 3+b

or,36= 3+b

or,36-3= b

or,33= b

therefore width is 33
