Question

The area of trapezium is 189cm lf the ratio of parallel sides is 2:7 and the distance between them is 14cm, find the length of p
arallel sides

Answer 1

let ║sides of trapezium are a=2x and b=7x

h=14cm

area of trapezium=189cm²

(a+b)h/2=189

(2x+7x)14=189×2

9x=189×2/14

9x=27

x=3

∴║sides of trapezium are

a=2x=2×3=6cm

b=7x=7×3=21cm
