Question

area of a Trapezium is 160 square centimetre length of a parallel side are in the ratio 1 : 3 smaller if parallel side is 10 cm and then find the perpendicular distance between them

Answer 1

And 8 cm 1/2×40×h=160 so now by solving tits h=8

Answer 2

Area of trapezium = 1/2 × (sum of parallel side) × distance between parallel line..

let the parallel line contains x
parallel are 1x and 3

distance between parallel line =10 cm

Are of trap. = 160cm^2

160 = 1/2 (1x+2x) × 10
160 = (1x+3x) × 5
160 = 5x+15x
160= 20x

x= 160/20
x = 8

parallel sides are ...1x = 8×1 = 8 cm
3x= 8×3=24cm
