Question

The area of a trapezium is 180 cm sq. and its height is 12cm .if one of the parellel side is double of that other find the other two parellel sides

Answer 1

one of the parallel side is 10cm and other is 20 cm

plz mark it as brainilest

Answer 2

Let the first parallel side be x and the second parallel side be 2x

Area of trapezium =

1/2×(sum of its parallel side)×Height

1/2×(x+2x)×12=180

1/2×(3x)=180/12

3x=15×2

3x=30

x=10

First parallel side is 10 and second is 20
