Final answer:
The perimeter of a parallelogram is the sum of all its sides. In this case, the parallelogram has two pairs of equal sides, so the perimeter is 2x + y.
Step-by-step explanation:
The perimeter of a parallelogram is the sum of all its sides. In this case, the parallelogram has two pairs of equal sides. Let's call the length of the sides ME and SOM as 'x' and the length of the sides BEM as 'y'.
Therefore, the perimeter will be ME + SOM + BEM + ME = x + x + y + x = 2x + y.
So, the correct answer is b. Perimeter = 2 × ME + 2 × SOM.
