The given triangle has a base of 4 feet, and the height is 8 feet.
To find the amount of paint used we need to find the area of the triangle .
Area of triangle can be found by the formula
A= [tex] \frac{1}{2} .base . height [/tex]
Area of the triangle =[tex] \frac{1}{2} (4)(8) =16 [/tex]
Area of triangle = [tex] 16foot ^{2} [/tex]
It takes 0.2 quart of paint to cover 1 square foot
To cover 16 square foot amount of paint used = 16(0.2)= 3.2 quarts.
Alberto uses 3.2 quarts of paint.
