Answer 2

9514 1404 393

Answer:

  (c)  90 m

Step-by-step explanation:

The perimeter is the sum of the side lengths. Each of the lower-right and lower-left indents can be reversed to make the figure a 20 m by 25 m rectangle without changing the perimeter. Then the perimeter is ...

  P = 2(L +W)

  P = 2(25 m + 20 m) = 2(45 m)

  P = 90 m

_____

If you start at the upper left corner and work clockwise, the perimeter is the sum of segment lengths ...

  P = 20 m + 5 m + 8 m + 20 m + 4 m + 20 m + 8 m + 5 m

  P = 90 m

__

The units must be given as part of the measurement of the perimeter. That is why choice B (90) is inappropriate.
