A cement walk of uniform width is built around a 20 foot by 40 foot rectangular pool and the area of the walk is 700 square feet. How wide will the walk be?

the pool has an area of
20*40=800
(20+2x)*(40+2x)=1500
positive answer only
x=5
the walkway will be 5 feet wide
check
30*50=1500
ok
why 2x? because the path is on both sides of the pool
