Question
A field is in the shape of a trapezium, where the
distance between the two parallel sides is 60 metres. One of the parallel sides measures 30 metres, and the total area of the field is 1680 square metres. What is the length of the other parallel side?Solution
Let the length of the other parallel side be 'x' metres.
Area of trapezium = (1/2) X (sum of parallel sides) X (perpendicular distance between parallel sides)
Or, 1680 = (1/2) X (30 + x) X 60
Or, 56 = 30 + x
So, 'x' = 26 m
