Question
If the ratio of height and base of a parallelogram is
8:5, respectively and its area is 640 cm2, then find the difference between height and base of the parallelogram.Solution
Let's assume the height and base of the parallelogram is '8x' cm and '5x' cm, respectively.
ATQ;
8x X 5x = 640
Or, 40x2 = 640
Or, x2 = 16
Or, x = 4 (since length cannot be negative therefore, we will take the positive root only)
Required difference = 8x - 5x = 3x = 3 X 4 = 12 cm
