1. D. 81 cm sq.
Shape: Square
Formula: P = 4s so 44 = 4s so s = 11 cm
Formula: A = s^2 so 11^2 = 121 cm sq.
2. £200
Shape: Square
Formula: P = 4s so P = 4(0.5) so P = 2 m
1 meter = 100 centimeters
So 2 m = 200 centimeters
3. 210 m
Shape: Triangle
Formula: P = a + b + c so P = 15 + 20 + 35 = 70 m
He travels around 3 times so 3x = 3(70) = 210 m
4. 150 m
Shape: Pentagon
# of Sides: 5
Formula: P = 5s so P = 5(30) so P = 150 m
5. 288 m
Shape: Rectangle
Formula: A = LW so A = 48 * 6 so A = 288 m
