Question

Find the perimeter and area of the shaded figure below. Explanation 1 unit Check 1 unit Perimeter = units Area = square units

Answer 1

Hello!

First, note that each square in the figure has a measurement of 1x1.

It means that the area of each square is 1unit².

Let's remember some important definitions to solve this exercise:

• Perimeter:, the sum of the measurement of all sides.

,

• Area of a rectangle:, length x height.

Knowing it, let's answer:

In the attached rectangle, we have:

• length: 4 units

,

• height: 2 units

Area:

$\begin{gathered} A=length\times height \\ A=4\times2 \\ A=8\text{ units}^2 \end{gathered}$

Perimeter:

The sum of the four sides is:

$\begin{gathered} P=length+height+length+height \\ P=4+2+4+2 \\ P=12\text{ units} \end{gathered}$

Answers:

• Area,: 8 units².

,

• Perimeter,: 12 units.
