Trapezoid + triangle - math problems

Trapezoid is a convex quadrilateral with one pair of parallel sides but referred to as a trapezium outside North America. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs or the lateral sides.

The trapezium
The trapezium is formed by cutting the top of the right-angled isosceles triangle. The base of the trapezium is 10 cm and the top is 5 cm. Find the area of trapezium.
