ANSWER
a=-2, b=3
EXPLANATION
The given equation is

Recall that:

We simplify the left hand side to get:

For this equation to be true, we must have:
-6a=12 and 2+b=5
This implies that,
a=-2 and b=3
X+6 = 3x - 12 (right?)
6 = 2x-12
18 = 2x
9 = x
4x-15 = 2x+3
2x-15 = 3
2x = 18
x = 9
Basically, x = 9
Answer:
area of rectangle = 120 cm²
area of triangle = 24 cm²
