MATH TRAIL
# 3
At
this station you will be working with AREA and PERIMETER. Area is the amount of space an object takes
up. Perimeter is the distance around an
object. Area is measured in SQUARE
units and perimeter is measured in linear, or line units. To find the area of a regular object, like a square or a rectangle, you need to know the length and width of the
object. To calculate the area you need to multiply the length by the width and
the result will be recorded in square units (inches, feet, centimeters,
whatever). The perimeter, or distance
around an object, requires the
measurement of all sides of the object and then adding the addends (lengths) to get the sum. If the object is a rectangle or a square, you simply measure the
length and the width and them multiply the sum by 2.
YOUR TASK:
Look
at the plaques that show the many awards and recognition that students,
faculty, the PTA and others have
received at Double Churches. Beginning at
the top left number the plaques from one to seven. Beginning with the first plaque find the area and the perimeter
of each plaque. Record the shape of the plaque on your grid paper, placing the plaques in a pattern to match their placement on the
wall. Show the lengths of all sides on
your drawings and write the calculated area in the center of your
diagrams. Were any of the plaques the
same size and shape? Did these plaques have the same area and perimeter? Did any of the plaques have the same
perimeter or the same area, but were
not the same shape?
