Hands-on math!


The perimeter of a figure is the total distance around the edge of the figure. For example, a square whose sides are 6 inches long has a perimeter of 6 x 4 = 24 inches because it has 4 sides 6 inches long.
A rectangle whose length and width are 4 meters and 3 meters has a perimeter of
4 + 4 + 3 + 3 = 14 meters.
Now, can you tell me what the perimeter of this rectangle?
    Perimeter = _______

Hint: Don't forget the sides that aren't labeled!

Now, here's a problem for you:
Find the perimeter of this shape made up of rectangles:

(label the 2 unlabeled sides first)

Perimeter = _____ m.
