PERIMETER AND AREA ACTIVITY SHEET
Perimeter (P) is the number of unit lengths around a figure.
Formula – Perimeter = (2 x length) + (2 x width) or P = (2 x l) + (2 x w)
Area (A) is the number of square units that cover a figure.
Formula – A = length x width
Example:
9cm
18cm
P = (2 x 18) + (2 x 9) Area = 18 x 9
P = 36 + 18 Area = 36
P = 54
Find the perimeter and the area.
1) l = 12 cm 2)
w = 9 cm 30cm
75cm
3) l = 100m 4) l = 18cm
w = 50m w = 10cm
5) Perimeter = 24 6)
L = 8cm 3.5cm
W = ? 6.9cm
You can multiply to change units of measurement from larger units to smaller units.
Example: 12 gal. = _____ qt. THINK: 1gal. = 4 qt.
12 x 4 = 48
12 gal. = 4 qt.
To change units of measurement from smaller units to larger units, you need to divide.
Example: 80 oz. = ____ lb. THINK: 1 lb. = 16 oz.
80 divided by 16 = 5
80 oz. = 5 lb.
Example: 27 in. = ____ ft. ____ in. THINK: 1 ft. = 12 in.
27 divided by 12 = 2 r 3
27 in. = 2 ft. 3 in.
Complete:
1. 7 lb. = ____ oz. 2. 9 gal. = ____ qt.
3. ____ lb. = 80 oz. 4. 80 in. = ____ ft. ____ in.
5. 9 yd. = ____ ft. 6. 70 pt. = ____ qt.
7. ____ lb. = 2.5 T 8. 28 qt. = ____ gal.
9. 3 ____ = 15,480 ft. 10. 45 in. = ____ ft. ____ in.
1 foot (ft) = 12 inches (in.)
1 yard (yd) = 36 inches
1 yard = 3 feet (ft)
1 mile (mi) = 5,280 feet
1 mile = 1,760 yards
1 pound (lb) = 16 ounces (oz)
1 ton (T) = 2,000 pounds
1 cup © = 8 fluid ounces (fl oz)
1 pint (pt) = 2 cups
1 quart (qt) = 2 pints
1 quart = 4 cups
1 gallon (gal) = 4 quarts
1 square foot = 144 square inches
1 square yard = 9 square feet
1 acre = 43,560 square feet
1 square mile = 640 acres
