Think about what you know about perimeter and area. Describe how to find the perimeter and area of your classroom.
To find the perimeter, you add all the sides together. To find the area, your multiply the width by height
To find the perimeter, I would use some device to measure the dimensions of my classroom the length and the width. Since I know the formula for perimeter 2(l+w), I can easily plug in the coordinates. To find the area of my classroom, I can use the measurements I originally took and multiply them , I*w, to get the area. Hope this helped ^-^
