Area Word Problems

Which bedroom is bigger?

If you said the one on the right, then you're correct! 👏

The bedroom on the right is bigger than the bedroom on the left.

It's easy to see that! 😎

But sometimes shapes look similar, so we need to find their **area **to really know which is bigger.

Do you remember what **area** means?

Areais the amount of space that a flat object or surface takes up.

We use area for **flat surfaces only**.

👉 We figure out the area by counting the **square units.**

👉 To know how big or small an area actually is, we use **units of area.**

Examples are **square centimeter or cm²**, and **square meters or m²**.

What is the area of this rectangle?

(1) First, we **note the measurement of each square**.

We see that it's 1 m long and 1 m wide.

This means that the area of each square is **1 m²**.

(2) Next, we **count all the squares **that the shape occupies or covers.

How many squares did you count?

That's right! 15 squares.

✅ The area of this rectangle is **15 m²**.

**🤓 How do we find the area of a space if we only know the width and length? **

Let's say we have a rectangle that has a width of 5 m, and a length of 3 m.

(1) Draw a grid.

👉 Start to color one square. Continue until you cover 5 squares to the right. This is the width.

Then, starting from the first square that you colored, color 2 more squares downward. This covers the 3 m for the length.

Continue to color sideways and downwards, until the two points meet and you complete the shape.

(2) Count all the squares that you've colored on the grid.

What did you get?

15 squares! That's **15 square meters** (or **15 m²**).

We don't always have time to draw grids, and to color squares.

So here's a faster way to find the area of a space.

Just **multiply** the width x height (or length), and you get the area!

5 x 3 = 15

That's 15 m²! We got the same answer, but we solved it faster this time.

Area is very important in real life. We use it to figure out many things.

Imagine you were trying to solve this problem.

Kim has a new sand box. He has to line its bottom with plastic. The box is 2 meters long and it's 3 meters wide. What is the area of the plastic that Kim needs for his box?

What do you need to do?

**Step 1.** ** Gather some clues**** **about the problem.

**Step 2.** ** Draw a grid **to show the measurements.

**Step 3.** Extend the length and width to **draw the complete shape**.

**Step 4.** ** Count the squares**.

**Step 5**. **Write your answer **in a word sentence.

The area of the plastic that Kim needs for his box is6 square meters or 6 m².

😀 Remember to always use the **correct unit of area.** 👍

Great work! Now, you can move on to practice. 💪
