Question

Mr. Wilson wants to build a square roof for his square deck in the back yard.

The roof will be 12 feet long on each side. He uses the formula (A = s) to
find the area of the roof. What will be the area of the square roof on Mr.
Wilson's deck? (give only the number value of your answer) *​

Answer 1

Answer: the area of the roof is 144 feet squared for each side (up and down), adding to a total of 288 ft^2

Explanation:

If the roof is a square with a side lenght L = 12 feet, then we use the fact that the area of a square is equal to the square of the side lenght of the square, this is:

A = L^2 = (12 ft)^2 = 144 ft^2

Now, Mr. wilson uses the equation A = s, this is because the roof has 2 surfaces, one up and one bottom, then the total area is 2 times the value that we find earlier:

2*144 ft^2 = 288 ft^2

Answer 2

The area of the square roof is 144 square feet.

Explanation:

Givens

• He wants to build a square roof.
• The roof will be 12 feet long.

We know that the area of a square is

`A=s^(2)`

Where
`s=12 \ ft`, according to the problem.

Replacing this value, we have

`A=(12 \ ft)^(2) =144 \ ft^(2)`

Therefore, the area of the square roof is 144 square feet.
