Note: Figure not drawn to scale If a = 18 ft, b = 24 ft, and c = 30 ft, what is the total area of the porch? Assume that the wooden part is a right triangle

Question

I do not know how to do this problem.

 

Answer 1

it's a 9 12 15 triangle. 15^2 = 225. 12^2 = 144 225-144= 81 9^2= 81

total area = A = hb/2 = height x base / 2

= 24 x 18/2 = 216
