So 6.50•2=13.00.
And 5.25•3=15.76. So add the 13.00 ,15.75 and the 15.25 and you get 44.00 so no he's a dollar short

System of equations:
w=(3/2)*h (1)
w*h=54 area (2)
w=54/h substitute into (1)
54/h=3h/2
3h²=54*2
h²= 36 (we take only positive solution)
h = √36=6
h=6 in.
w=(3/2)*h=(3/2)*6= 9
w=9 in.
correct answer is D
