Question:
The perimeter of a parallelogram is 22 cm. If the longer side measures 6.5 cm what is the measure of the shorter side?
Solution:
Let the shorter side be 'x'.
Therefore, perimeter = x + 6.5 + 6.5 + x [Sum of all sides]
22 = 2(x + 6.5)
11 = x + 6.5
⟹ x = 11 - 6.5 = 4.5 cm
Therefore, shorter side = 4.5 cm
