Often, you will be asked to solve problems involving geometric relationships or other shapes. For realworld problems, those geometric relationships mostly involve measurable attributes, such as length, area, or volume.
Sometimes, those problems will involve the perimeter or circumference, or the area of a 2dimensional figure.
For example, what is the distance around the track that is shown? Or, what is the area of the portion of the field that is covered with grass?
You may also see problems that involve the volume or surface area of a 3dimensional figure. For example, what is the area of the roof of the building that is shown?
Another common type of geometric problem involves using proportional reasoning.
For example, an artist created a painting that needs to be reduced proportionally for the flyer advertising an art gallery opening. If the dimensions of the painting are reduced by a factor of 40%, what will be the dimensions of the image on the flyer?
In this resource, you will investigate ways to apply a problemsolving model to determine the solutions for geometric problems like these.
A basic problem solving model contains the following four steps:
Step 1: Read, understand, and interpret the problem.

Step 2: Make a plan.

Step 3: Implement your plan.

Step 4: Evaluate your answer.
