Question

the area of a trapezium is 540 cm square .if the ratio of parallel sides is 7:5 and the distance between them is 18 cm, find the lengths of parallel sides

Answer 1

Answer:

Step-by-step explanation:

Let the parallel sides be 7x and 5x

Area=540cm^2

Height=18cm

area of trapezium=1/2×sum of parallel sides×height

540=1/2×(7x+5x)×18

540=12x ×9

540/9=12x

60=12x

x=5

Parallel side= 5x=5×5=25cm

7x=7×5=35cm
