Question

A trapezium of area 105 cm2 has parallel sides of
length 5 cm and 9 cm. How far apart are the
parallel sides?

Answer 1

Answer:

Given values

Area of Trapezium = 105 cm²

Parallel sides :-

a = 5 cm

b = 9 cm

Height ( h ) = ?

Area of Trapezium = 1/2 ( a + b ) h = 105

===> 1/2 ( 5 + 9 ) h = 105

===> 1/2 ( 14 ) h = 105

===> 7 × h = 105

===> h = 105 / 7

===> h = 15 cm

Height of the parallel sides is 15 cm .
