Given:-

Area of Trap.=850²cm

1st Parallel side=64cm

Height=17cm

__________________________________

Let, Other parallel side be x cm:-

$Area\:of\:Trap.=\frac{1}{2}×(Sum\:of\:Parallel\:Sides)×H$

$Area\:of\:Trap.=\frac{1}{2}×(64+x)×17$

$850×2=(64+x)×17$

$1700²cm=(64+x)×17$

$\frac{1700}{17}=64+x$

$100cm=64+x$

$100-64=x$

$=>36cm=x$

Hence ,other parallel side is 36cm
