Question

A4. In trapezium ABCD, AB = 2 cm, BC = 10 cm, DC = 10 cm and AB is parallel to DC. Find the perimeter and area of the trapezium.​

Answer 1

Let ABCD be a trapezium.

so, AB=2cm , BC=10cm , DC=10cm and DA=10cm.(asBC = DA)

so, perimeter=

(2+10+10+10)cm

32cm

&

Area=

1/2×(2+10)×10 cm²

=1/2×12×10 cm²

=1/2×120 cm²

=60 cm²

Hope it's help you.
