Answer:
length of one parallel side =31m
length of other parallel side = x
height = distance between parallel sides = 52m
Area of trapezium = 1/2 * ( sum of parallel sides) * height
2470 = 1/2 * (31 + x )* 52
2470 = (31 + x) * 26
2470/26 = 31 + x
95 = 31 + x
95-31 = x
64 = x
length of other parallel side = 64m
