Question

the area of trapezium is 660 cm square and the length of one parallel side is 25 cm if its height is 40 cm find the length of other parallel side​

Answer 1

Step-by-step explanation:

We know that the area of a trapezium

½×(sum of parallel sides)×height

then,

height = 30cm

area = 660cm²

one side = 28cm

let another side = x

then.

½×(28+x)×30 = 660

=> 14+x/2 = 22

=>x/2 = 22-14

=>x = 8×2

=>x = 16

Then the length of another parallel side of trapezium is 16cm.
