Finding Missing Side Lengths in Rectangles

This video tutorial teaches how to find the missing side length of a rectangle when the area and one side length are known. It covers three examples, each increasing in complexity, demonstrating the use of multiplication and division to solve for the missing side. The video also explains how to handle remainders in division, converting them into decimal form for precise measurements. By the end, viewers are encouraged to apply these methods to solve similar problems independently.

What is the main focus of the video tutorial?

• Finding the missing side length of a rectangle

• Calculating the area of a rectangle

• Learning about different shapes

• Finding the perimeter of a rectangle
