Answer: 9x+36
Explanation:
Area=length times width which would be length: 3/4x+3 times width which is 12.
12 times 3/4x is 9x
Then you need to do the same for 12 times 3 which is 36.
So I believe it is 9x+36.
Answer: The correct answer is 9x+36
Area of the rectangle:
short side: 12
long side: 3/4x + 3
area = 12 * (3/4x + 3)
area = 12*3/4x + 12*3
area = 36/4x +36
area = 9x + 36
