Question

the area of trapezium is 15.4 m square if one of the parallel side is 5m less than twice the other parallel side and the distance between them is 1.4 M find the length of both the parallel sides

Answer 1

Let first parallel side be x

So other parallel side = 2x - 5


Given that area = 15.4
Height = 1.4


We know that, area of a trapezium

= 1/2 × (sum of parallel sides) × h = area

=> 1/2 × (x + 2x - 5) × 1.4 = 15.4

=> (3x - 5) × 0.7 = 15.4

=> (3x - 5) = 15.4/0.7

=> (3x - 5) = 22

=> 3x = 22 + 5

=> 3x = 27

=> x = 27/3

=> x = 9 m



So other parallel side = 2x - 5 = 2(9) - 5 = 18 - 5

= 13m


Answer :- 9m and 13m

Answer 2

Answer:

The correct answer will be 9m and 13m
