Question

please give correct answer.

Answer 1

Perimeter of the figure is 130 m

Given the side AD, BC, DC as 42, 54, 19; the fourth side will be 130 - (42+54+19) = 15 m

As AB is perpendicular to the parallel sides, it means that it is the height of the trapezium.

Area of a trapezium is given by 1/2 * (Sum of the 2 parallel sides) * Height

=1/2 * (54+42) * 15

=720 $m^{2}$
