Answer:
66x
Explanation:
Separate the shape into a rectangle and a triangle.
Dimension of the rectangle:
Dimension of the triangle:
- base = (15 - 11) = 4
- height = (7x - 4x) = 3x
Area of a rectangle = length × width
Area of a triangle = 1/2 × base × width
Total area = area of rectangle + area of triangle
= (15 × 4x) + (1/2 × 4 × 3x)
= 60x + 6x
= 66x
