Ryder is building a workbench.
the top of the workbench is a rectangular piece of plywood that is 6.25 feet long and 1.83 feet wide.

part a
round the length and width to the nearest whole number.
then estimate the perimeter of the workbench.
which of the following equations models this estimate of the perimeter?
a. 6 + 6 + 2 + 2 = 16
b. 6 × 2 = 12
c. 7 + 7 + 2 + 2 = 18
d. 7 × 2 = 14

part b
round the length and width to the nearest tenth.
then estimate the perimeter of the workbench.
which of the following equations models this estimate of the perimeter?
a. 6.2 + 6.2 + 1.8 + 1.8 = 16
b. 6.2 × 1.8 = 11.16
c. 6.3 + 6.3 + 1.8 + 1.8 = 16.2
d. 6.3 × 1.8 = 11.34
