Answer 1

The perimeter is the distance around.
The perimeter of a the rectangle is
P = (2 * 8 1/2) + (2 * 3 3/4)

What do you get?

Answer 2

P = (2 * 8 1/2) + (2 * 3 3/4)

4P = 390

P = 195
2
= 97.5
Am I correct?Or what did I do wrong! Please explain.

Answer 3

How did you get this? 4P = 390

P = (2 * 8 1/2) + (2 * 3 3/4)

P = 17 + 7 1/2

P = 24 1/2
