Question

The area of trapezium is 420cm and its hight is 14cm if length of one parallel sides is double of other parallel find the length of parallel sides

Answer 1

Step-by-step explanation:

area of trapezium is equal to half multiply sum of parallel sides multiply height

420 is equals to 1 upon 2 multiply sum of parallel sides multiply 14

if one parallel side is equals to X then an other parallel side is 2x

420:=7(x+2x)

420/7:=3x

60=:3x

60/3=x

20 =x

one side is equals to 20 and another side is equals to 40 because of 2x
