Question

The area of trapezium is 248cm² and its height is 8m.If one of the parallel sides is smaller than the other by 4m find the length of the two parallel lines...​

Answer 1

Given:

Area of trapezium= 248 m? Height (h)= 8 m

Let the one parallel side be= x m Other parallel side =( x-4) m

Area of trapezium = 1/2 (sum of parallel = sides) x height

248 = 1/2 (X+ X- 4)x 8

248 = (2x - 4) x 4

248/4 = 2x-4 =

62 = 2x-4

62+4= 2x

66= 2x

X= 66/2

X= 33
