Question

the area of the trapezium is 3150 m square and its parallel side is 85 M if the distance between the parallel side is 45 M find the other side

Answer 1

let one parallel side be x
area of trapezium=1/2*sum of parallel sides*distance between parallel sides
                     3150=1/2*85+x*45
                     6300=3825+45x
                     2475=45x
                     2475/45=x
                             55=x
