S=4lw+2wh; s=180, l=8, w=5

Step-by-step explanation:

from the question it was given to be

S=4lw+2wh

given that,

S = 180

L = 8

w=5

solution

S=4lw+2wh

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=4lw+2wh

S = 4 (8 * 5) + 2 (5 * 2)

S = 160 + 20

S = 180
