Given:
There is a pair of parallel sides in the given figure.
To find- the area of the shape.
Explanation-
Since two sides are parallel and the others are non-parallel, the shape is a trapezium.
The formula of the area of a trapezium is -
From the given figure, the height is 24 units, and the parallel sides are 3 and 10, respectively.
Substitute these values in the formula, and we get
Thus, the area of the given shape is 156 units².
The answer is 156 units².
