Answer:
Length of the smaller parallel side is 24..
Step-by-step explanation:
Given: parallel sides are in the ratio 3:5
Therefore, let the parallel sides of the trapezium be 3x and 5x respectively..
ATQ,
ar. of trapezium = 1/2 (sum of parallel sides) h
384 = 1/2 (3x +5x) 12
384 = 1/2 (8x) 12
384 x 2 = (8x) 12
768/12 = 8x
64 = 8x
64/8 = x
8 = x
Hence, 3x = 3(8) = 24 cm
5x = 5(8) = 40 cm
