Find the perimeter ( I am not sure of the step) Can someone help me PLease
If a rectangle whose dimensions ar e8 1/2 in.x 3 3/4 in.
am I to multiply because this is what i got 0.020564475m^2 please get me going in the right direction .
Thank you in advance for the help.

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?
posted by Ms. Sue

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.posted by Anonymous

How did you get this? 4P = 390
P = (2 * 8 1/2) + (2 * 3 3/4)
P = 17 + 7 1/2
P = 24 1/2posted by Ms. Sue
