A rectangular sheet of paper measures 8.5 inches by 11 inches. Ava is calculating its area in square

ft. The first step of Ava's work is shown below.

__________________

From inches to feet

12 in = 1 ft

x in * 1ft/ 12 = y ft

__________________________________

A= 8.5 in * 11 in

A= 93.5 sq in * (1ft/ 12 in)^2 = 93.5 sq in * (1ft/ 144 in)

or

Area = (8.5 in* 1ft/ 12 in) x 11 in*( 1ft/ 12 in)

Area = (0.71 1ft) x ( 0.92 ft)

____________

2. Which equation follows directly from step 1 to find Ava's solution in the correct units?

A Area = 8.5 in x 11 in ( FALSE inches)

B Area = in x in

с Area = 8.5 ft x 11 ft ( FALSE the given units are in )

D Area = 8.5/ 12 ft x 11 / 12 ft (This is the answer)
