Part 1
Estimate the area of the mural. Choose the correct answer below.
A.
10 ftsquared
B.
13 ftsquared
C.
12 ftsquared
D.
11 ftsquared

Answer 1

First round the dimensions: 2 3/7 ≈ 2 and 4 1/2 = 4.5 ≈ 5, so estimated area = 2 × 5 = 10 ft². (Answer A.)

Exact area:
2 3/7 = 17/7, 4 1/2 = 9/2
Area = (17/7) × (9/2) = 153/14 = 10 13/14 ≈ 10.93 ft².
