Question

The area of trapizium is 279sq cm .the distance between its parallel sides 18 cm and one of the parallel side is 13 cm .find the other length of other side

Answer 1

Step-by-step explanation:

let one parallel side be x then another one is x+5

now, area=1/2 (sum of ll side)×height (distance)

279=1/2(x+x+5)×18

558=(2x+5)×18

31=(2x+5)

2x=26

x=13 and another ll side is 13+5=18 ans

Answer 2

The area of trapizium is 279sq cm .the distance between its parallel sides 18 cm and one of the parallel side is 13 cm .find the other length of other side.

Good question,

Here is your perfect answer!

Area of a trapezium = 1/2 * (sum of parallel sides) * height

=) 279 = 1/2 * (13+x) * 18

=) 279*2/18 = (13+ x)

=) 31 = 13 + x

=) 31-13 = x

=) x = 18 cm.

Here x = other side.
