Answer:
Step-by-step explanation:
from the question it was given to be
S=4lw+2wh
given that,
S= 180
L= 8
w=5
solution
180 = 4(8×5) + 2(5×h)
we will evaluate first for the value of h
180 = 4(40) + 2(5h)
180 = 160 +10h
collect the like terms
180-160 =10h
20 = 10h
divide both sides by 10
20/10 = 10h/10
2 = h
to check if your answer is correct
S = 4( 8× 5) + 2(5 ×2)
S =160 + 20
