since, the formula of area of a trapezium is "o.5(or 1 upon 2)x sum of parallel sides x height" so u have the parallel sides but u need to find the height between the parallel sides. otherwise your formula with existing information will be "1/2 x (60+77)x height(not mentioned)
area=1/2 x 137 x h(height consider it as h)
area=78.5 x h
area=1/2 x 137 x h(height consider it as h)
area=78.5 x h
