Nazm's sister also has a trapezium shaped plot. Divide it into three parts as shown. Show that the area of trapezium `WXYZ = hfrac(a+b)(2)`

Mohan wants to buy a trapezium shaped field. Its side along the river is parallel to and twice the side along the road. If the area of this field is 10500m^2 and the perpendicular distance between the two parallel sides is 100m, find the length of the side along the river.

A tent is in the shape of a cylinder surmounted by a conical top.If the height and diameter of the cylindrical part are 2.1m and 4 m respectively,and the slant height of the top is 2.8 m,find the area of the canvas used for making the tent.Also find the cost of the canvas of the tent at the rate of Rs.500 per m^2 (Note that the base of the will not be covered with canvas).

Area of a trapezium is 1350 m^2 and sum of the lengths of its parallel sides is three times the height. Find the height.

The shape of the top surface of a table is a trapezium. Find its area if its parallel sides are 1m and 1.2m and perpendicular distance between then is 0.8 m.
