Question

The
area of a trapezium is 810 cm?
of the parallel sides is 3:1. of the distance
between
the parallel sides is 27cm find their
lengths.

Answer 1

Answer:

Let the parallel side of trapezium be x & 3x cm respectively

Area=160 cm^2

Short parallel side=x=10 cm

Short parallel side=3x=3*10 =30 cm

1/2(a+b)*h=160

1/2(10+30)*h=160

1/2*40*h=160

20*h=160

h=160/20

h=8 cm

Therefore, perpendicular distance between them is 8 cm.
