Answer:
Superficie de un prisma rectangular fórmula
Área de un prisma rectangular = 2la + 2ah + 2lh.
Step-by-step explanation:
P=4s
s=p/4
a=s^2, using s found above
a=p^2/16, we were told that p=40 so
a=40^2/16
a=100 in^2

Step-by-step explanation:
Put 8 in the formula and do the arithmetic.
A8 = 2·8 +7 = 16 +7
A8 = 23
The area of the new square is 9k. For example if in the original square, each side was 2, then k=4. 2*3=6 so each side would be 6 long. 6*6 is 36 so the new square's area is 9 times the original.
