Question

The lengths of the parallel sides of a trapezium are 8.7 cm and 5.3 cm. If the perpendicular distance between them is 4.5 cm, what is its area?

Answer 1

area of parallelogram=1/2×sum of parallel side×height
=1/2×(8.7+5.3)×4.5
=1/2×14×4.5
=7×4.5
=31.5sq cm

Answer 2

Since the area of the trapezium can be found by the equation 1/2*(a+b)h

We can substitue here,

Area of trapezium= 1/2*(8.7+5.3)4.5

=31.5 sq. cm
