1. ## Perimeter of rectangle.

Use the following information to answer #4.

A rectangle has length of 5.5 m and width of 3.5 m.

4. a. Find the perimeter and area of a rectangle with a length of 5.5 m and a width of 3.5 m.
b. Double the width of the rectangle and determine the perimeter of the new rectangle.

c. What happened to the perimeter of the rectangle when the width was doubled?
d. Make a prediction. What happens to the perimeter of the rectangle if both the length and the width are doubled?

e. The original rectangle has a width of 3.5 m. Double the width and determine the area of the new rectangle.
f. Make a prediction. What happens to the area if both the length and the width are doubled?
g. If the length was tripled, and the width was doubled what would happen to the area? Show an example to support your answer.

What have you tried? Where are you stuck?

3. Perimeter equals to the sum of its lengths and widths.
4. a. 2(5.5 m) + 2(3.5 m) = 11 m + 7 m = 18 m
b. 2(5.5 m) + 2²(3.5 m) = 11 m + 14 m = 25 m
