what is the perimeter of a 40 in rectangle

Question

I dont understand how to do this .

Answer 1

1) Either your rectangle perimeter adds up to 40 inches

 

OR

 

You do not have enough information.
Look at your problem again and check for Length and Width.

Perimeter = 2L + 2W

 

For example if;

Length = 15

Width = 5

 

then

Perimeter = 2(15) + 2(5) = 30 + 10 = 40

 

I hope this helps you
