A. To solve for the perimeter P, we need to isolate it on one side of the equation.
S = Ph + 2B
Subtract 2B from both sides:
S - 2B = Ph
Divide both sides by h:
(P = (S - 2B)/h)
So the equation solved for P is:
P = (S - 2B)/h
B. We know that the height of the rectangular prism is 4 meters, the surface area is 96 square meters, and the base area is 8 square meters. We can use the equation from part A to solve for the perimeter.
P = (S - 2B)/h
P = (96 - 2(8))/4
P = (96 - 16)/4
P = 80/4
P = 20
Therefore, the perimeter of the base of the rectangular prism is 20 meters.
