Question

Explaining the area of rectangle

Answer 1

Hello!

First, let me draw a rectangle:

• length: 5 cm

,

• width: 3 cm

To obtain the area of a rectangle, we will have to use the formula below:

`\text{Area}=\text{length}\cdot\text{width}`

So, as we know its values, we just have to replace them in the formula:

`\begin{gathered} \text{Area}=5cm\cdot3cm \\ \text{Area}=15cm^2 \end{gathered}`

Let me explain it in another way:

In the image, we have some squares inside the rectangle, right?

Each square corresponds to 1cm² of area. If we count all inside the rectangle, we will obtain:

• 5cm² in the first line

,

• 5cm² in the second line

,

• 5cm² in the third line

If we sum all of them, we will have the same 15cm² that we obtained in the formula.
