Area of a triangle:
A= (1/2)(bh)
In this problem we are given:
A= 178.5
b= h+4 in
h= UNKNOWN ("h")
Plug in our values into the area equation and solve for "h":
(multiply each side by 2 to get rid of the 1/2)
(357/21=17)
(solve both inequalities separately)
( a negative height is not possible so, this answer is incorrect.)
Answer: base = (h+4)= (17+ 4) b= 21 in h= 17in
