Answer 1

Solution :-

Let the parallel sides of the trapezium-shaped field be ′ x ′m and ′2x′ m.

Let a=x and b=2x and h=100m

Then, its area=

1/2×(a +b)× h m^2 = 1/2× ( x + 2x)× 100 ×m^2 = 50× 3 m^2 = 150x m^2

But it is given that

the area of the field is =

$10500 \: {m}^{2}$

∴150x = 10500

[tex]

⇒x=10500/150 =70

∴ The length of the side along the river is =

2×70 = 140m.

Your answer is 140 m .
