Answer:
A = Ph + 2B
Step-by-step explanation:
where P is perimeter of the base, h is height of the prism (this is the rectangular lateral surface area) and B is the area of the base
2(bh + lh + hb)
<R = 158
Supplementary angles equal 180 degrees.
<Q + <R =180
22 + <R = 180
Subtract 22 from each side
22-22 + <R = 180-22
R = 158
