Given
Area of a trapezium is 180 cm^2. One parralel side is longer than the other by 6 cm. The altitude is 9 cm.
To Find
Length of each side.
Assumption
Let one parallel side be x cm
Other parallel side = x + 6 cm
Answer and explanation
Area of a trapezium is altitude into sum of parallel sides divided by 2
That is
So put the values in it
Thus x = 17 cm
So other side is x + 6 = 17 + 6 = 23 cm
