Answer: $1980

Step-by-step explanation:

Well, based off of the question being asked, I assume that you will need to pay $11 for 90 square footage of tiling, and then the same for the other square footage of tiling. Therefore your answer will be $1980. If you are looking for the equation, it is (11x90)=990   (990)2 = 1980

you do not need to multiply 11 by 90 again because you already know the answer.

Answer:

$110

Step-by-step explanation:

We are given that

Cost of 1 square yard of floor tile =$11

We have to find the cost of 90 square feet of tile.

To find the cost of 90 square feet we will convert it into square yard.

We know that

9 square foot=1 square yard

1 square foot=[tex]\frac{1}{9}[/tex]

90 square feet=[tex]\frac{1}{9}\times 90=10[/tex] square yard

By unitary method

Cost 1 square yard=$11

Cost of 10 square yard=[tex]11\times 10=[/tex]$110

Hence, the cost of 90 square feet to tile a bathroom=$110
