Well the area of a trapezoid is defined by the following formula:
A = \frac{1}{2}(b_{1} + b_{2})h where b₁ and b₂ are the bases of the trapezoid and h is the height of the trapezoid.

Let's plug in what we know into this formula:
h = 7  the perpendicular distance between the two bases
b₁ = 15  the shorter parallel side
b₂ = 25  the longer parallel side made up of 4 + 15 + 6
so, A = \frac{1}{2} (15+25)(7)=140

This is in square units of measure of course, so 140 in²
