The width of the Ochoa community pool is 20 feet. The length is twice as long as its width. What is the perimeter of the pool?
Nevermind my question above, it was stupid.
The perimeter is 100 ft. because there are 4 sides and two are 20 feet long and the other 2 are 40 feet long (40, because the length is twice as long as the width, which is 20), and 20+20+40+40=100.
20x2=40 , so we now know the length. Cause 2 sides are in the shape, we do (20x2)+(40x2)=120 as the perimeter. It just like adding 8 and 4 together.
