Answer:
option A. 36 square inches
Step-by-step explanation:
The figure is a trapezium
Area of a trapezium=1/2 *(sum of parallel sides) *height
From the diagram, the parell sides are 6 inches and 12 inches ,and the height is 4 inches.
We substitute these values into the formula.
This implies that, the area
[tex] = \frac{1}{2}(6 + 12) \times 4[/tex]
[tex] = \frac{1}{2}(18) \times 4[/tex]
[tex] =9\times 4[/tex]
[tex] = 36[/tex]
Thus the area is 36 square inches
