Lilah Chang · Answer 1

A=LW, area equals the product of the length times the width, so we can say:

W=A/L, we are told that A=45/4 and L=9/2 so:

W = (45/4) / (9/2) ft

W = (45/4) * (2/9) = 90/36 ft

W=5/2 ft

W=2.5 ft.

Bugsy · Answer 2

Area = length * width

45/4 = 9/2 * width

width = (45/4) : (9/2)

= 5/2 feet
