The shape of the top surface of a table is trapezium. Its parallel sides are 1 m and 1.4 m and the perpendicular distance between them is 0.9 cm. Find its area.
Given
Length of parallel sides is 1m and 1.4m
Height (h) = 0.9m
We know that area of trapezium is 
× (sum of parallel sides) × height
Therefore Area of trapezium = 
× (1 +1.4) × 0.9
=1.08 m2.
