The diagram shows a field in the shape of a trapezium. $AB=150m,BC=90m$ and $CD=120m$.
Angle $ABC$ = angle $BCD$ = $90^{\circ}$.

i) Show that $AD=95m$, correct to the nearest metre.

ii) A fence is built around the perimeter of the field.
It costs $\$48$ to build each 5-metre section of the fence.
Calculate the cost of building this fence.
