Question

the parallel sides of trapezium are in the ratio 7:11 and the distance between them is 35 cm . if the area of trapezium is 1260 cm sq find the length of parallel sides​

Answer 1

Answer:

Step-by-step explanation:

Let the length of the parallel sides be (7x)cm and (11x)cm

Area of the trapezium=(1/2)×(sum of parallel sides)×(distance between them)

306 cm²=(1/2)×(7x+11x)×17

306=(1/2)×(18x)×17

306=153x  ⇒x=306/153=2 cm

Length of the parallel sides=7x=7×2=14 cm

                                           11x=11×2=22 cm

solve similarly,,
