Answer:
Step-by-step explanation:
Length of parallel sides of the trapezium are in ratio 7:5
Distance between the parallel side is 14cm
Area of trapezium is 1/2 x (sum of parallel sides) x height
Therefore 252 is equal to 1/2 x (7 +5) x height
252 is equal to 6x x height
Height is equal 252/6x
Height equal to 42
Therefore length of the parallel side is 6 and 6
