Question

the lengths of parallel sides of a trapezium are in the ratio 7 :5 and the distance between them is 14cm if the area of the trapezium is 252cm² find the length of its parallel sides

Answer 1

Answer:hope it helps

Step-by-step explanation:

Answer 2

Answer: 15 cm and 21 cm

Step-by-step explanation: area of trapezium = 1/2 × sum of aprallel sides × height

let parallel sides be 7x amd 5x

sum = 12x

area = 1/2 × 12x × 14

[ Height is given as 14 cm]

area = 84x

but are is given as 252 sq cm

so 84x=252

x = 3

parallel sides were 5x and 7x

or (5×3) and (7×3)

15 cm and 21 cm
