Answer:
18 square yards of rubber flooring
Explanation:
We can look at the model as a 16x13 rectangle with a 6x9 rectangle cut out of it. So we can just find the area of the 16x13 rectangle and subtract the area of the 6x9 rectangle:
16*13=208
6*9=54
208-54=154
So the area of the floor is 154 square feet.
BUT the problem asks how many square YARDS of rubber flooring are required to cover the floor. Because there are 3 feet in a yard, there are 3^2 square feet in a square yard, or 9 square feet in a square yard. So we need to divide 154 by 9, which is 17 1^9. Because you can only buy 1 square yard of rubber flooring at a time, we need to buy 18 yards of rubber flooring to cover the floor.
I hope I explained this well enough. Happy mathing!
Edit: I just stood up too fast. The second picture is VERY true.
