cm and the other sides are 25 cm
and 26 cm
The area of a
the parallel
rapezium is 105 cm'. If one of the parallel sides is 20 cm and the distan
is 5 cm, find the length of the other parallel side.
of the trapezium PART whose side
is 28 cm and the distance between
i the area of the​

Answer 1

Answer:

area of trapezium = 1/2 * h(sum of parallel sides)

here we don't know one side x

1/2*h(20+x)

=1/2*5(20+x)

x=5/2-20

x=5/2-40/2

x=35/2

x=17.5

then area=1/2*5*37.5

=93.75cm^2
