3.4444444 because u only need to divide 137 by 45

because of the distributive property and exponent laws.
I would double check if I were you! Hope this helps!
Area, A = Width, W* Height, H
Therefore,
W = A/H
Options:
At H = 4 ft, W = 60/4 = 15 ft
At H = 5 ft, W = 60/5 = 12 ft
At H = 6 ft, W = 60/6 = 10 ft
Quarters?
because there are four? and they're equal?
