Chapter 10: Problem 55

Using words only, describe how to find the perimeter of a rectangle.

Short Answer

Expert verified
To find the perimeter of a rectangle, you need to add the lengths of all its sides. This can be done by doubling the sum of the rectangle's length and width, according to the formula \(2 \times (length+width)\).

Step by step solution

01

Understand what perimeter means

Perimeter is the term used to describe the distance around something. In the case of a rectangle, it's the total length of all its sides.
02

Identify the dimensions of a rectangle

A rectangle has two dimensions: length (typically the longer side) and width (the shorter side). These dimensions are not the same, which is what differentiates a rectangle from a square.
03

Apply the formula for the perimeter of a rectangle

The formula to calculate the perimeter of a rectangle is \(2 \times (length+width)\). This formula takes into account all four sides of the rectangle: two sides of length 'length' and two sides of length 'width'.
04

Generalize the result

No matter the specific measurements, the perimeter of a rectangle can always be found using this formula. So, if only the general method to find the perimeter is required, then one just needs to understand and apply this formula.

In the diagram for Exercises \(17-19\), suppose that you are not told that \(\triangle A B C\) and \(\triangle A D E\) are similar. Instead, you are given that \(\overleftrightarrow{E D}\) and \(\overleftrightarrow{C B}\) are parallel. Under these conditions, explain why the triangles must be similar.

The rungs of a ladder are perpendicular to each side, so the rungs are parallel to each other.
