25cm
eg for perimeter 🔲 25cm you can do 20 + 20 + 20 + 20 = 80 then 5+ 5 + 5 + 5 =20 80 + 20 = 100 cm
5cm
eg for area 🔲 5cm you can do 5 x 5 = 25cm squared
To find the perimeter you need to add all of the lengths together.
To find the area of squares and rectangles you need to times length by width.
