Answer:

thank u

Step-by-step explanation:

2(l+w)=112.8

l+w=112.8/2

36.9+w=56.4

w=56.4-36.9

w=19.5

Answer:

W = 19.5

Step-by-step explanation:

substitute the given values into the equation

112.8 = 2(36.9 + W) ← divide both sides by 2

56.4 = 36.9 + W ( subtract 36.9 from both sides )

19.5 = W
