The frame is a rectangle that’s 16 inches by 20 inches. the craft store has 7 feet

Hi!

Imagine a rectangle with a width of 20 inches, and a height of 16. Find the length around the rectangle (the perimeter).

16+20+16+20=72

There are 12 inches in a feet. How many feet are in 72 inches?

72/12=6

Lana needs 6 feet of ribbon. She bought 7 feet.

7-6=1

It is enough ribbon.
1 foot will be leftover.

Hope this helps! :)

The answer is 12.6 %.
60% = 60 / 100 = 0.6

 60% of 21
= 60% * 21
= 0.6 * 21
= 12.6
