When finding the area of plane figures you need specific measures. One of the greatest lessons for students is deciding what information they have given and which formula they need to use to find the area of the plane figures. Below are multiple plane figures and the formula(s) needed to find areas.
Area can also be found on a coordinate plane using order pairs to find necessary dimensions.
