Answer:

the surface area of the prism is equal to 202 m^2

Explanation:

The surface area of the prism is equal to

SA=2B+Ph

where

B is the area of the base

P is the perimeter of the base

h is the height of the prism

Find the area of the base B

B=LW=4*5=20m^2

Find the perimeter of the base P

P = 2(L+W) = 2 (4+5) = 18 m

Find the surface area ---->

SA = 2B + Ph = 2(20) + 18(9) = 202 m^2

btw m^2 is stand for square meter, also called the meter squared! (just if ur wondering)
