34 inches
Step-by-step explanation:
A doormat is the shape of a rectangle and its area uses A=l*w. If the area is 714 and its length is 21, then 714 = 21*w. Solve for w.
714=21w
714/21= 21w/21
34 = w
Multiple: 3 * 2 = 6
Subtract: 12 - 6 = 6
Multiple: 100 * 6 = 600
Add: 15 + 600 = 615
Add: 615 + 6 = 621
