A man needs to repaint the two triangular gables on his house. Each gable is long and high. How many gallons of paint will he need if a gallon of paint covers 100 sq. ft.? (You must buy whole gallons).

A) 2 gallons
B) 3 gallons
C) 264 gallons
D) 132 gallons

"Each gable is long and high."

Do you have the measurements?

To find out how many gallons of paint the man will need, we first need to calculate the total area of both triangular gables on his house.

The formula for the area of a triangle is:
Area = (base * height) / 2

Since both gables are triangles, we need to calculate the area of each gable separately using the given dimensions.

Let's assume the dimensions of the first gable are:
Base = b1
Height = h1

The area of the first gable will be:
Area1 = (b1 * h1) / 2

Similarly, let's assume the dimensions of the second gable are:
Base = b2
Height = h2

The area of the second gable will be:
Area2 = (b2 * h2) / 2

To find the total amount of paint needed, we need to calculate the sum of the areas of both gables:
Total Area = Area1 + Area2

Finally, we can divide the total area by the coverage of one gallon of paint (100 sq. ft.) to find the required number of gallons:
Number of gallons = Total Area / Coverage of one gallon

Let's calculate the area and find the answer:

Assuming the dimensions of the first gable are:
Base = 20 ft
Height = 10 ft

The area of the first gable is:
Area1 = (20 ft * 10 ft) / 2 = 100 sq. ft.

Assuming the dimensions of the second gable are:
Base = 15 ft
Height = 8 ft

The area of the second gable is:
Area2 = (15 ft * 8 ft) / 2 = 60 sq. ft.

The total area is:
Total Area = 100 sq. ft. + 60 sq. ft. = 160 sq. ft.

To find the number of gallons needed, we divide the total area by the coverage of one gallon of paint:
Number of gallons = 160 sq. ft. / 100 sq. ft. = 1.6 gallons

Since we can only buy whole gallons, the man will need to buy 2 gallons of paint (nearest whole number).

Therefore, the correct answer is:
A) 2 gallons
