I'm not sure about the answer, but this is how I would do it, since 15% and $150 are the same based on the question. do let me know if it's right! :)
Answer:
I think answer is 87<180 or maybe 87<12*15
A' = (1/2)*A = (8, 0)
B' = (1/2)*B = (12, 6)
C' = (1/2)*C = (6, 8)
The third choice is appropriate.
Are there any answer choices ?
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= 17inPlease comment with any further questions! :)
