Answer:
The area of the figure is C. 146 cm²
Step-by-step explanation:
The figure contains trapezium and a triangle.
Area of the figure = Area of trapezium + Area of triangle
So, the area of the trapezium is given by
Area =
1/2 x (a + b) x h
1/2 x (14 + 4) x 10
1/2 x 18 x 10
= 90 cm²
Height of triangle is given by
18 - 10 = 8cm
The area of the triangle would be
1/2 x base x height
1/2 x 14 x 8
= 56 cm²
The total area of the figure is given by
90 + 56 = 146 cm²
So, C is correct.
