let non parallel sides be x
40 m +30m+x+x = 110
2x = 110- 70
x = 40/2=20m
draw a perpendicular from any upper point
by using pythagoras
(10)²+ (height)²= (20)²
100+(height)²= 200
height= √100 = 10
= area = 1/2(a+b)* h
= 1/2(30 + 40)*10
= 1/2*70*10
= 350m²
40 m +30m+x+x = 110
2x = 110- 70
x = 40/2=20m
draw a perpendicular from any upper point
by using pythagoras
(10)²+ (height)²= (20)²
100+(height)²= 200
height= √100 = 10
= area = 1/2(a+b)* h
= 1/2(30 + 40)*10
= 1/2*70*10
= 350m²
