Question

find the lengths of the parallel sides.
10. The area of a trapezium is 0.05 m2 and its height is 20 cm. If one of the parallel sides is shorter than
the other by 8 cm, find the length of the longer parallel side,​

Answer 1

Answer:

0.05m^2=0.05*10000=500cm^2

Step-by-step explanation:

area of trapezium= 0.05m^2=0.05x10000cm^2=500cm^2

let longer side=x,then shorter side=x-8 cm

area of trapezium =1/2*(base1+base2)*height

500cm^2= 1/2*(x+x-8)*20 cm

500cm^2/10cm=2x-8

50cm +8 = 2x

58 cm/2 = x

or, x = 29cm

longer side = x=29cm

shorter side = x-8=29-8=21cm
