Question

The area of a trapezium is 1100sqm the distance between two parallel sides is 20m and one of the parallel side is 70m find the length of the other parallel side

Answer 1

Formula for calculating the area of a trapezium
Area = 1/2 x (s1+s2) x distance between the parallel sides
1100 = 1/2 x (70 + x) x 20 
110= 70 + x 
x = 40m
