Find the length and the width of the parallelogram

Question

 The perimeter of a parallelogram is 68 meter.  The  width the parallelogram is 2 mmeter less than its length.  Find the length and the width of the parallelogram.

Answer 1

The perimeter of a parallelogram is 68 meter

P = 2w + 2l = 68m = 68,000mmeter

The width the parallelogram is 2 mmeter less than its length.

w = l - 2mmeter

68000 = 2(l - 2) + 2l

68000 = 2l - 4 + 2l

67996 = 4l

l = 16999 mmeter

w = 16997 mmeter
