Answer:
13.89 inch
Step-by-step explanation:
area = length x width
=> width = area/length = 108.35/7.8 = 13.89 inch
y = dresser height
x = mirror height
x+y=6.28
x-y = 1.28
x = 1.28+y
(1.28+y)+y=6.28
2y = 5
y = 2.5
Dresser = 2.5 ft
Dresser + Mirror = 2.5 + 1.28 = 6.28 ft
Mirror = 1.28 ft
it say the answer is 4 but I don't know how
the answer is 9.95
