Question

the area of a trapezium is 248 sq .m and its height is 8 m if one of the parallel side is smaller than the other by 4 m find two parallel sides

Answer 1

area = 248 sq.m
let one side = $
other side = $ + 4
h = 8m
area = 1/2( $ + $+4)8
248 = 4( 2$ + 4)
248 = 8$ + 16
248-16 = 8$
232/8 = $
one side = 29
other side = 29 + 4 = 33
