The area of a trapezium is 34 cm2 and the length of one of the parallel sides is 10 cm and its height is 4 cm. Find the length of the other parallel side.
It is given that,area of trapezium = 34 cm2 and height = 4 cm
Let the length of one parallel side be a. We know that,
Area of trapezium = `1/2` (Sum of parallel sides) × (Distances between parallel sides)
`34 cm^2 = 1/2 (10 cm + a) xx (4 cm)`
34 cm - 2(10 cm + a)
17 cm = 10 cm + a
a = 17 cm - 10cm = 7 cm
Thus, the length of the other parallel side is 7 cm.
