Triangular region is 6.8f and the base is 8.5f. plywood was painted with paint cost $0.80 per square foot,what was the cost

Question

of the amount of paint needed to coat one side of the triangle?

Answer 1

If you meant that the height of the triangular region was 6.8f, then a solution is possible.

 

The area of a triangle is 1/2BH. Therefore A = (8.5f x 6.8f) / 2 = 28.9f²

 

The Area 28.9f² x $0.80/f² = $23.12
