Answer 2

Answer:

area of the following polygon

= area of trapezium EDCB + area of triangle AED

area of the following polygon

= 1/2 x sum of parallel sides x height

+ 1/2 x base x. height of triangle AED

height of trapezium = 13-8 = 5cm

area of the following polygon

=. 1/2 x (12+6) x 5 + 1/2 x 6 x 8

=. 1/2 x 18 x. 5. + 1/2 x 6 x 8

= 9 x 5 + 6 x. 4

= 45. + 24

= 69cm²
