Answer:Area of triangle is 2xx + 18x + 36 square units
Step-by-step explanation:
We are not given the value of x.
So we express the area in terms of x.
Using the formula for a triangle, we have:
Area = A = (1/2)*base*height
A = (1/2)*(4x + 12) *(x +6)
There are no units given so I will assume the Area units are "units squared"
Let us distribute the (1/2) into the binomial (4x + 12)
We get: (1/2)*4x + (1/2)*12 = 2x + 6
Area = A = (2x + 6) *(x + 6) , use distributive property
A = (2x + 6)* x + (2x + 6)*6
A = 2*x*x + 6x + 12x + 36
A = 2x*x + 18x + 36
