<p>A square lot that is enclosed by a fence has fence posts at each corner. There are 10 fence posts on each side of the square lot. What is the total number of fence posts on the lot?</p>
<p>I don't have the answer for this question.
Could someone explain to me how to solve this question?</p>
<p>Whoever wrote this question (probably) wants you to imagine a square lot with ten posts on each of the sides. It’s a matter of adding the posts up and not counting the corner posts twice. The answer is not 40.</p>
<p>this isn’t too bad, you just need to visualize it. since a square has 4 congruent sides, just do 10 (from each side) x 4 (# of sides) = 40, then subtract 4 for repeated corners (by doing 10 x 4, you’ve included each corner twice), so yeah, 36.</p>
