Question

the area of a pool is 12 square units and the area of the walkway around the pool is 60 square units, what is the perimeter of the walkway?

Answer 1

not enough data

all we know is that the total area of pool plus walkway is 72 units^2

so
9x8=72 , perimeter = 34
6x12 = 72 , perimeter = 36
4x18 , perimeter = 44
etc
