We divide the trapezium into 3 parts: 2 triangles and a rectangle.

$\sf \: Base\:of\:triangle= = \frac{20 - 10}{2} = 5$

Height of triangle and rectangle.

H²=13²-5²

H²=169-25

$\sf \: H = \sqrt{144} = 12$

Area of trapezium=

$\sf \frac{(20+ 10)}{2}\times 12 = 180$

So area of trapezium is 180 cm²
