Your students will become junior math detectives as they hunt down the missing side of a rectangle by applying the area formula for rectangles. The only clues they have are the rectangle's area and the measure of one side.

Young mathematicians will enjoy demonstrating their skills with this lesson on finding area. It addresses the concepts of length, width, and square units.

You need the length and the width to find the area of a rectangle or square, but what if one piece of information is missing? Use this lesson alongside What's My Area? or on its own.
