Answer 1

Rezercet) (Thousands of $ ----- - - Expenser 27 - - - 20 Time (Dam) Area of Quadrilateral = area Ae area B Area A = = area of rectangle (60-20) x (2-0) = 40x2 = 80 Area B = area of a = = x 160-20) (6-2) 4x40x42 = 40x2 = 80 Area of ou adrilateral = 80t 80 معده و کا 165 = 160,000

pиe и od 2 -c (so, 6) - - - p (20, 2) А (20,о) В (Go, o) area of quonde lateral ABCD = area of ABD + area of двер

Area of by the ABD and concept of ABCD can be determinent found { f(x, , 92 s( X2, 9,) 8 (3, 9а) оча three non- wllinean point than алоа о д і тиалл bИ 2 It this value comer -ue then we take Absolute value beealue area is atю Шаач. Now area of a ABD ( 20, ), B( 60, 6), D (2012) 20 о ) ) 20 2 | 20 (о - 2) - о + ( 120 ~0) 1 = 4 - чо + 10) - х 80 = ҷо

алое оf 4 В СФ В(Goo) C ( 60, 62, p(202) 5 | 26 2 6o (6-2) – о + ( 120 = ( 24o +о) – туҷо = 12-о area of quadrilateral ABCD = 40 +120 = 160 thousand от 16о, ооо Hence, the we result can ure any method but will be same.
