Question

A picture frame (rectangle) has a length of 8.5 inches and a perimeter of 38 inches.


How would you find the width of a picture frame. (Use words). And what is the width, show your work?

Answer 1

The answer is 10.5 inches for width

First you can add 8.5 + 8.5 = 17 because the opposite side of the 8.5 is also 8.5.

After You have to divide subtract 17 from 38 which equals 21. Then you divide by 2 which equals 10.5.

For perimeter you need to add all the sides so we add 8.5 + 8.5 + 10.5 + 10.5.
