Aswimming pool has a perimeter of 72 feet. the short sides measure 16 feet. what is the length of the longer sides of the pool?

The length of the longer sides is 20 feet.

Hope this helps!

P=72 feet
short sides= 16 feet
(I wrote that down to help me sorry)
First to solve this you need to add 16 and 16. 
16+16=32
Then to find the longer legs you have to subtract 32 from 72.
72-32=40
Divide 40 by 2
40/2=20
Each long leg is 20 feet long
Check: 20+20+16+16= 72

They sought new allies to germany tried to get mexico to join and put pressure on the us. the us joined the allies because of the lucitania
