Question

2) The area of Bethany's rectangular yoga mat is 15 square feet. The width of her mat is 3 feet. How many feet long is Bethany's yoga mat?

A) 2 feet
B) 6 feet
5 feet
D) 7 feet

Answer 1

C-5 feet

Explanation:

If the area is 15, and the width is 3, we need to find the length with the info we have. And we know, to find the area, we need to multiply the length and the width. What number times 3 can get us to 15? Let's find out by dividing.

15/3=5

How to check? Use inverse operations:

3*5=15

Answer 2

5 feet

15 divided by 3 is 5

Area is base x height so 3 x 5 is 15
