Compare the estimates to the exact perimeter.


The estimate using measurements rounded to the nearest whole number is closer to the exact perimeter.

The estimate using measurements rounded to the nearest tenth is closer to the exact perimeter.

The two estimates are equally close to the exact perimeter.

Neither estimate is close enough to the exact perimeter to be useful.

Answer 1

Part A: C

Part B: B

Part C: 15.91

first round the 2 numbers by the tenths. Then round the numbers by ones(whohle number). After that, since ther are four sides we do 12.63 + 3.28 + 12.63 + 3.28 which equals to 15.91.
