What is the estimate number of small shaded square needed to go around the edge of the rectangle?

I don’t have the picture or the rectangle’s dimensions — can you upload the image or tell me the rectangle’s length and width (and the side length of a small shaded square)?

Meanwhile here’s how to estimate it:

- If the rectangle fits an integer number of the small squares along its sides, let m = number of small squares along the length and n = number along the width. The number of small squares needed to make a single-square-thick border around the rectangle is
total = 2m + 2n − 4
(each corner would otherwise be counted twice, so subtract the 4 corner duplicates).

- If the rectangle’s sides are lengths L and W and each small square has side s, then
m = L/s, n = W/s (if those are integers). If not, use m = ceil(L/s), n = ceil(W/s) to ensure the border covers the whole side, then use the same formula total = 2m + 2n − 4.

Example: L = 10, W = 6, s = 1 → m = 10, n = 6 → total = 2·10 + 2·6 − 4 = 32.

Send the picture or the values L, W, s (or counts along one side) and I’ll compute the exact estimate.
