Answer:
Step-by-step explanation:
Alright, lets get started.
We first need to find the surface area of the ramp without its base.
The ramp consists 4 sides two triangles and two rectangles.
Area of 1 triangle = \(\frac{1}{2}*14*6=42\)
Area of 2 triangle = 42
Area of top rectangle = \(15.2*19.5=296.4\)
Area of back rectangle = \(6*19.5=117\)
So total area = \(42+42+296.4+117=497.4\) square feet
We are asked to paint two coats of paint means we have to double the area.
So the double area is = \(2*497.4=994.8\)
80 square feet requires = 1 quart of paint
994.8 square feet requires = \(\frac{994.8}{80}=12.435\)
12.4 quart can't be purchased so complete number of quart will be 13 quart. : Answer
Hope it will help :)
