Question

geometry, measurement, data analysis perimeter and area on a grid find the area and perimeter of the shaded figure below. 1 unit 1 unit area = square units perimeter = units

Explanation:

Step1: Calculate the area

Count the number of unit - squares in the shaded region. There are 9 unit - squares. So the area $A$ of the shaded figure is given by the number of unit - squares it contains. $A = 9$ square units.

Step2: Calculate the perimeter

Count the number of outer - sides of the unit - squares that form the boundary of the shaded region. Each side of a unit - square has a length of 1 unit. By counting, we find that the perimeter $P$ is 12 units.

Answer:

Area = 9 square units
Perimeter = 12 units
