The length of side along the river is 68 m

Step-by-step explanation:

Area of trapezium = 10200 m²

Length of side along the road (a) = x

Length of side along the river (b) = 2x

Height = 200 m

We need to find Length of side along the river.

The formula used is: $Area\: of\: trapezium=\frac{a+b}{2}\times h$

Putting values and finding length:

$Area\: of\: trapezium=\frac{a+b}{2}\times h\\10200=\frac{2x+x}{2}\times 200\\10200=2x+2\times 100\\\frac{10200}{100} =2x+2\\102=3x\\x=\frac{102}{3}\\x=34$

So, Value of x = 34

Length of side along the road (a) = x = 34

Length of side along the river (b) = 2x = 2(34) = 68

So, the length of side along the river is 68 m
