Step-by-step explanation:
Given data
Robound= 70%

=0.7*400
=280cm
Hence the new height after the rebound is
I don't get it, what are you suppose to do?

40 feet would have been if the perimeter was 160ft. so since it has to be less than 160 the maximum (whole number) length of a side would be 39.
13.9 ft
