Question

only for Genius....give the answer

The Area of a trapezium is 480 m² The distance between two parallel line is 15 m and one of the parellel side is 20 m find the other parellel sides

Answer 1

Area of a trapezium : (sum of parallel sides/2)*height
let other parallel sides be x
so we get,
480 = ({20+x}/2)*15
480/15 ={20+x}/2
(480*2) / 15=20+x
(960/15)-20=x
64-20=x
44=x
other parallel sides =44m

Answer 2

Here is your answer.
Area of trapezium :(sum of parallel sides/2)*height
let the other parallel side be x
So,we get
480=({20+x/2)}*15
480/15 ={20+x}/2
(480×2) / 15 =20+x
(960/15)-20=x
64-20=x
44=x
Therefore,other parallel sides is 44.
Hope it helps you.
