a field in the shape of trapezium . one of its parallel side is twice the other parrallel side and distance between them is 100m .if the area of field is 10500m² find the length of parrallel sides

a field in the shape of trapezium . one of its parallel side is twice

1.	a field in the shape of trapezium . one of its parallel side is twice the other parrallel side and distance between them is 100m .if the area of field is 10500m² find the length of parrallel sides
Answer» -step explanation:LET the parallel sides of the trapezium-shaped field be ′ x ′ mand ′ 2X ′ m.Let a=x and b=2x and h=100mThen, its AREA.= 21 (a+b)×hm 2 = 21 (x+2x)×100m 2 =50×3xm 2 =150xm 2 But it is given that the area of the field is 10500m 2 ∴150x=10500⇒x= 15010500 =70∴ The LENGTH of the side ALONG the river is 2×70, i.e., 140m.
