Question

Two parallel sides of a trapezium are 85 cm and 63 cm and its area is 2664cm2 . Find its altitude .

Answer 1

Let its height/altitude be h.

We know that,
Area of Trapezium
=1/2×(sum of parallel sides)×height

According to the question,

1/2×(85cm+63cm)×h=2664cm²

1/2×148cm×h=2664cm²

74cm×h=2664cm²

h=2664cm²/74cm

h=36cm


Therefore the altitude is 36cm.
