Heya mate!!! I really loved your question... here is the answer of it:
Given, ABCD is a trapezium and side AB || side DC
l(AB) = 13 cm, l(DC) = 9 cm, l(AD) = 8 cm.
Area of trapezium = ½ x sum of lengths of parallel sides x height
= ½ x [l(AB) + l(DC)] x l(AD)
= ½ x [13 + 9] x 8
= ½ x 22 x 8
= 11 x 8 = 88 cm
Thus, the area of the trapezium ABCD is 88 sq. cm
have a great day ahead friend! : )
