A parking lot is 144.3 m long and 47.66 m wide. What is the perimeter of the lot?

Given the length of the parking lot L = 144.3m
Width of the parking lot w = 47.66m
Total number of significant figures in each of the given values is 4
Therefore the answer should have four significant figures.
Now we have perimeter = 2(length + width)
