1. Rounding to the nearest foot gives a perimeter of
2 × 12 + 2 × 14 = 24 + 28 = 53 feet
2. The dimensions of the room given as mixed numbers is:
[tex]13 \frac{2}{3} \: feet \: by \: 12 \frac{1}{4} \: feet[/tex]
3. The actual perimeter of the room is
2(13×12+8) inches + 2(12×12+3) inches
= 328 inches + 294 inches = 622 inches
=
[tex]51 \frac{5}{6} \: feet[/tex]
4. Calculating My estimated perimeter - My actual perimeter yields a difference of
[tex] = 52 \: feet \: - 51 \frac{5}{6} \: feet \: = \: \frac{1}{6} \: foot[/tex]
