Area of a Trapezium

The trapezium has two parallel sides and two non-parallel sides

Since sides of lengths 7, 5 are parallel and perpendicular to the side of length 4. Thus the trapezium has bases b1=7, b2=5, and height h=4.

The formula to calculate the area of a trapezium is:

$A=(b1+b2)/(2)\cdot h$

Substituting:

$A=(7+5)/(2)\cdot4=(12)/(2)\cdot4=24$

The area of the shaded region is 24 square units
