If both sides of a gable roof are the same size, and one side of the roof measures 15'x 36*, how many squares of 16" x 5/2" wood
kogti [31]

Approximately 3 shingles used to cove the area of the roof.

According to the statement

we have to find the number of shingles used to cover the roof.

So, For this purpose, we know that the

one side of the roof measures 15'x 36

And we have given that the both sides of a gable roof are the same size.

So, For this purpose,

The roof is a of a rectangle shape so,

Area of rectangle = 2(L+B)

Then

Area of rectangle = 2(L+B)

Area of rectangle = 2(15+36)

Area of rectangle = 102 ft.

Then

Area of shingles = 2(L+B)

Area of shingles = 2(16+2.5)

Area of shingles = 37

then number of shingles used = 37/102

So, Approximately 3 shingles used to cove the area of the roof.
