Answer:
The longer side is 19 cm
Step-by-step explanation:
Let the longer side be x.
Smaller side = (x - 8) cm
Height = 8 cm
Area = 120 cm^2
Area of a trapezium = [Height (Smaller side + Longer side)] / 2
120 = 8 {(x - 8) + x} / 2
120 = 4 {x - 8 + x} [4, as 8 is divided by 2 in the denominator]
120 / 4 = 2x - 8
30 = 2x - 8
30 + 8 = 2x
38 = 2x
38 / 2 = x
19 = x
Thus, the longer side is 19 cm.
