Question

7. The length of a rectangle is 12 in. and the perimeter is 56 in. Find the width of the rectangle. A. 22 in. B. 16 in. C. 32 in. D. 21 in

Answer 1

I believe the answer would be b. I think this is because you know that the perimeter is the length times 2 and the width times 2 added together. If you do 12 times 2 you get 24. Then you subtract this from 56 because 56 is the perimeter of the whole thing. Then after this you get 32.Then divide 32 by 2 to find ONE of the widths.
