Which of the shapes has perimeter of 90? rectangle or semicircles?

anonymous · Answer

I think it is the semicircles... I was able to figure this out. 
P= (pi*x)+(pi*y)

isaiah.feynman · Answer

So its the semicircles that has the perimeter 90??

anonymous · Answer

no, im sorry. the rectangle is suppose to have P=90
