Lesson 6: Decompose figures to find area# Area: FAQ

Frequently asked questions about finding area.

## What is area?

Area is the amount of space a two-dimensional, or a flat, shape covers.

## What's the distributive property and how does it help us find area?

The distributive property tells us that we can break a multiplication problem into two smaller problems and then add the results together. This can be really helpful when we're trying to find the area of a shape that's made up of two or more smaller shapes.

## How do you find the area of a rectangle?

If a shape is made up of unit squares, we can count the number of squares to find the area. So, for example, if a shape is made up of $8$ unit squares, the area is $8$ square units.

To find the area of a rectangle, we multiply the length by the width. So, for example, if a rectangle has a length of $6$ inches and a width of $4$ inches, the area is $6\times 4=24$ square inches.

## How can we find the missing side length of a rectangle if we know the area and the other side length?

We can use the formula for the area of a rectangle to solve for the missing side length. For example, if we know that the area of a rectangle is $24$ square inches and the width is $6$ inches, we can set up the equation $6\times x=24$ and solve for $x$ to find that the length is $4$ inches.

## Why do we need to learn about area?

Area is a really important concept in math, and it's used in a lot of real-world situations. For example, if you're painting a room, you need to know the area of the walls in order to figure out how much paint to buy.

- Geometry is used in architecture, interior design, and construction for stable and visually appealing structures. Navigation, maps, and route planning rely on geometry to calculate distances and plan efficient paths. Artists and designers apply geometric shapes and patterns for visual harmony in their works. That is why geometry is important to us in real life.(7 votes)
