In This Video on Area of Squares and Rectangles

Zuri and Freddie are upgrading their home, but want to make sure the items will fit. To do this, they need to learn about finding the area of rectangles and squares. They eventually find an item that will fit inside their home! At the end of this, you will find area of squares and rectangles worksheets.

How to Find the Area of Rectangles and Squares

Finding the area of squares and rectangles is a simple process. The formula for finding area is area = length x width.

First, you count the unit squares along the length. Then you count the unit squares along the width. Finally, you multiply the length by the width to find the area. In the below example, the length is five, and the width is three. We multiply them to get fifteen, which is our area!

Finding the Area of Rectangles and Squares Summary

Remember, to find the area of rectangles and squares, use the formula area = length x width. Count the length, then count the width, and finally multiply them together to find the area. Below you will find an area of rectangles and squares worksheet.

Transcript Area of Rectangles

Zuri and Freddie are getting ready to hunt for some new items for their home. They need help determining the area of some items, so they can decide if they will fit or not. To do this, we will find the area of rectangles. Area is the amount of space taken up by an object on a flat surface. To calculate the area of rectangles we can use a multiplication formula; area equals length times width. First, count the unit squares along the length, replacing length with this number. Next, count the unit squares along the width, replacing width with this number. There are five unit squares in every row and we have three rows, so we need to find five multiplied by three! That means we multiply the length by the width to find the area of the rectangle. Five multiplied by three is fifteen, so this rectangle would be fifteen square units. Let's calculate the area of Zuri and Freddie's home first so they know how much space they have. Here is the floor plan. Remember the formula; area equals length times width. First, count the unit squares along the length, which is six. Now count the unit squares along the width. Multiply six by four, which is twenty-four! Zuri and Freddie's home is twenty-four square units. It looks like Freddie has found a rug, so let's help find the area! Remember; area equals length times width. What is the first step? Count the unit squares along the length. How many unit squares is the length? It is seven. What is the next step? Count the unit squares along with the width. How many unit squares wide is the rug? It is four unit squares wide. Now calculate the area. What is seven times four? It is twenty-eight, so the rug has an area of twenty-eight square units! "Hmm, that's probably not going to fit because our home is only twenty-four square units. How about this?" Zuri found a coffee table, so let's calculate the area! The formula for calculating area still works here because a square is also a rectangle! Use the formula, area equals length times width. What is the multiplication sentence for the area of the coffee table? It is two times two. What is two times two? It is four, so the area of the coffee table is four square units! "That will fit perfectly, Zuri!" While Zuri and Freddie finish up, let's review. Remember, to calculate the area of rectangles you can use area equals length times width. First, count the unit squares along the length. Next, count the unit squares along the width. Finally, multiply the length by the width to find the area. "Freddie, what are you doing?" "The rug may not fit our home, but it sure makes a great royal cape to be king for a day!"
