One roll of astroturf will cover 150 square feet. find how many rolls should be purchased to cover a lawn that is 22 ft. x 31 ft.?

Hello!

First you have to find the area of the lawn

To do this you do l * w

22 * 31 = 682 square feet

Then you divide it by the amount of space one roll of AstroTurf covers

682/150 = 4.5

Since you can't by a half of a roll we round this up to 5

He will need 5 rolls of AstroTurf to cover the lawn

The answer is 5

Hope this helps!
