The great thing about the "fancy" quadrilaterals (squares, parallelograms, rectangles, rhombuses, AND trapezoids) is that they all have the same area formula.
Area = (base)(height)
In the case of a trapezoid, there are two bases (the two parallel sides are considered the bases).
So, what do we do?
We use the average of the two bases
This figure features a trapezoid.
The bottom base has length 5 and the top base has length 2
So, the average of the two bases = (5+2)/2 = 3.5
So, the area of the figure = (base)(height) = (3.5)(2)
= 7

The figure consists of
a square with side 2,
a triangle1 with height=base=2,
and a triangle2 with a height=2 and base=1.
The combined area
= Area of Square(2*2) + Area of triangle1(\(\frac{1}{2}*2*2\)) + Area of triangle2(\(\frac{1}{2}*2*1\))
= 4+2+1 = 7(Option A)
