Question

If the smallest side of a trapezium is 10 metre and distance between the two parallel sides of the trapezium is 20 m and also its area is 480m² , find the other side of the trapezium.​

Answer 1

Answer:

Step-by-step explanation:

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
