Question

find the perimeter and area of each figure. show work! 1) perimeter =__ area = 2) perimeter = area =__

Explanation:

Step1: Count unit - length sides for perimeter

Count the number of unit - length sides along the outer boundary of the figure. Each small square has a side - length of 1 unit.

Step2: Count unit - squares for area

Count the number of unit - squares within the figure. Each small square has an area of 1 square unit.

For the first figure:

• Perimeter: By counting the outer - side lengths, we find there are 16 unit - length sides. So the perimeter is 16 units.
• Area: By counting the number of unit - squares inside the figure, we find there are 10 unit - squares. So the area is 10 square units.

For the second figure:

• Perimeter: Counting the outer - side lengths, we get 20 unit - length sides. So the perimeter is 20 units.
• Area: Counting the unit - squares inside the figure, we have 13 unit - squares. So the area is 13 square units.

For the third figure:

• Perimeter: Counting the outer - side lengths, we find 22 unit - length sides. So the perimeter is 22 units.
• Area: Counting the unit - squares inside the figure, we get 14 unit - squares. So the area is 14 square units.

Answer:

1. Perimeter = 16, Area = 10
2. Perimeter = 20, Area = 13
3. Perimeter = 22, Area = 14
