Question

The two parallel sides and the distance between them, of a trapezium are in the ratio 3:5:2. If the area of the
trapezium is 392 cm²; find its height and the parallel sides.​

Answer 1

Answer:

let parllel sides be 3x and 5x

and height be 2x

Step-by-step explanation:

area of trap.= 1/2*h(sum of // sides)

392=1/2*2x(3x+5x)

392=8x^2

x=√392/8

x=7

parllel sides 3(7) and 5(7)

21cm and 35 cm

distance b/w them = 2(7)

=14cm
