Answer 2

Answer:

Perimeter of Trapezium = Sum of sides

Let a and b be the parallel sides of trapezium.

Perimeter = Sum of sides

104 = 18 + 20 + a + b

104 = 38+ a + b

a + b = 104 - 38

a + b = 66

Area of Trapezium =

$\frac{1}{2} (a + b) \times h$

$\frac{1}{2} \times 66 \times 16$

$528{m}^{2}$
