Use Structure: A triangle has a base of 4x + 12 and a height of x + 6. Write a simplified expression for the area of the triangle using the formula A = 1/2 bh. Then find the area of the triangle when x = 7 millimeters.

• A = 1/2(4x + 12)(x + 6), Area = 126 mm²

• A = 2 (4x + 12)(x + 6), Area = 105 mm

• A = 1/2 (4x - 12)(x - 6), Area = 147 mm
