DO NOT WRITE OR DRAW on the paper with all the shapes on it.

    Measure the sides of the shapes with your ruler.
    Calculate the perimeters and areas of the shapes using the formulas listed on page 46 in the manual.
    As fractions, NOT decimals
    Type in your answers as mixed numbers in the form below.

    Example: if your answer is 4 1/4, type 4 1 4 into that row of the form.

    If time permits, try finding the perimeters and areas of the shapes on the back side of the page.

    For the perimeters, add up all of the sides.
    For the areas, cut out regular shapes (rectangles and triangles) and add them up.
    For #7 and #8, punch out (subtract) the smaller shape from the bigger shape.
