Answer 2

Answer:

its area is 180 cm²

Step-by-step explanation:

let its height be x from point D to base AB on a point P as well as from point C to base AB on point Q

it will form a rectangle PQCD and also 2 triangles APD and BCQ

now from triangle APD by formula H²=P²+ B²

P²=H²-B²

P²=13²-5²

P²=169-25

therefore P=12

or height = 12 cm

now area of trapezium=½ × height ×( AB + CD)

=½ × 12 ×(20+10)

= 6 × 30

= 180cm²...ans
