Perímetro

Perimeter: the sum of the measurements of all sides of a shape. To calculate the perimeter of a shape, you first need to know the measurements of all sides. Where do we use perimeter in our daily lives? To buy wire and build a pet pen, we first need to know the perimeter size. When we're renovating a house, for example, to buy the right amount of baseboards, we must measure the perimeter of the room. That is, add the measurement of each side, not forgetting to subtract the measurement of the doors, since baseboards aren't used on doors, right? And if you want to decorate the pool with balloons around it, you first need to know the perimeter of the pool to know how much string to buy.
