Question

Natalie plans to have tile put on her kitchen floor the area to be covered with tile is 12 1/2 feet long and 11 feet wide. natalie calculates the area and adds an additional 10% to make sure she has enough tiles.

What is the area of square feet of a natalie's floor including the additional amount?

Answer 1

I'm not positive about this, but I think the answer is 137500.

To find the area, multiply 12.5 times 11. Then set up a proportion to find the extra 10%.

12.5 x 11 = 137.5

137.5 10
? 100

137.5 x 100 = 13750
13750/0.10 = 137500

Hope this helps!! :)
