Example 9.26 from Prealgebra, 9.4 Use Properties of Rectangles, Triangles, and Trapezoids

Use Properties of Rectangles, Triangles, and Trapezoids: example 9.26

Each of two square tiles is $1$ square inch. Two tiles are shown together.

ⓐ What is the perimeter of the figure?
ⓑ What is the area?

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
ⓐ The perimeter is the distance around the figure. The perimeter is $6$ inches.
ⓑ The area is the surface covered by the figure. There are $2$ square inch tiles so the area is $2$ square inches.

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Find the ⓐ perimeter and ⓑ area of the figure:

A rectangle is shown comprised of 3 squares.
