Question

The length of the parallel sides of a trapezium are in the ratio 5:3 and the distance between them is 12.5 cm.If the area of the trapezium is 450 cm²,find the length of the parallel sides.

Answer 1

Answer:

length of parallel sides=5:3

let length of parallel sides be 5x and 3x

then

area of trapezium =1/2×(a+b)×h

(a+b)=5x ,3x

h=12.5

area=450cm sq

area of trap=1/2×(a+b)×h

1/2×(5x+3x)×12.5=450

1/2×8x×12.5=450

4x ×12.5=450

4x=450/12.5

4x=36

x=36/4

x=9

9×5=45

9×3=27

length of parallel sides=45,27
