Line segments around a rectangle

Count of line segments to wrap around a rectangle

This math skill teaches how to calculate the number of smaller line segments required to wrap around the perimeter of a rectangle. The method involves first determining the rectangle's perimeter and then dividing it by the length of one segment to find the total number of segments needed.

How many of the smaller line segments will wrap around this rectangle

The distance around a shape is its perimeter, so let's calculate our rectangle's perimeter

Plugging in our dimensions, we have a perimeter of 30

Since perimeter is a length, and our segment has a length, we can just divide one length by the other to get the segment count.

So we have 10 segments that would wrap around the rectangle.
