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) *

Step-by-step explanation:

Givens

We know that the area of a square is

Where , according to the problem.

Replacing this value, we have

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

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

Step-by-step 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

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
