Question

find the area and perimeter of the shaded figure below. area = square units perimeter = units

Explanation:

Step1: Count unit - squares for area

Each small square has an area of 1 square unit. Counting the shaded squares, there are 9 shaded squares. So the area is calculated by multiplying the number of shaded squares by the area of one square.
Area = 9×1 = 9 square units

Step2: Count outer - side lengths for perimeter

Count the number of outer - side lengths of the shaded figure. Each side length of a small square is 1 unit. The shaded figure has 12 outer - side lengths. So the perimeter is 12×1 = 12 units.

Answer:

Area = 9 square units
Perimeter = 12 units
