Question

Area of a trapezium is 4875 cm square whose one of the parallel sides is 3.02 m in length . if the distance between the parallel sides is 25 cm find the other parallel sides

Answer 1

Step-by-step explanation:

Correct option is

A

84

Given:

Area of the trapezium =1586 cm

2

Distance between the parallel sides =26 cm

And, length of one parallel side =38 cm

Let us suppose the length of the other side to be x cm.

Now, area of the trapezium =

2

1

× (Sum of the parallel sides)× (Distance between the parallel sides)

⇒1586=

2

1

×(38+x)×26

⇒1586=

2

26

×(38+x)

⇒13×(38+x)=1586

⇒38+x=

13

1586

⇒38+x=122

⇒x=122−38=84 cm

Hence, the length of the other parallel side is 84 cm.
