the area of a rectangle is 100 square inches. the perimeter of the rectangle is 40 inches. a second rectangle has the same area but a different perimeter. is the second rectangle a square? explain why or why not.

No
P=2(a+b)
A=a*b
You can construct infinity numbers of rectacangles wit area 100 in^2
A=2*50=100
A=4*25=100
A?5*20=100 etc
