The parallel sides of a trapezium are 28 cm and 16 cm and its area is 220 cm2. The distance between its parallel sides is
a) 5 cm
b) 10cm
c) 15cm
d) 20cm

Answer 1

A=(1/2)h(B+b)

220=(1/2)h(28+16)

220=(1/2)h(44)

220=22h

h=220/22

h=10 cm which is b)

Answer 2

Hi Nvljdzvlzq,

 

You have      ½(28+16)h=220 that is area formula for a trapezium. Can you take it from here?
