Question

If the area of a trapezium is 960sq,cm and height is 20cm. if one parallel side is double the other parallel side, then what is the shorter parallel side is ?
please help me

Answer 1

Step-by-step explanation:

let the one parallel side be x. then, the other parallel side be 2x.

1/2(x+2x )20=960

10×3x = 960

x = 96/3

hence, x= 32.

one parallel side=32 cm

other parallel side = 32×2 =64 cm.
