# Area without Grids

## Area - How it Works - Video

### Example 1

Example 1:

For this example, the length is 4 cm and the width is 2 cm. To find the area of a rectangle, one way is to use the area formula which is Area = Length x Width. If we substitute the numbers into the equation, we will get Area = 4 cm x 2 cm. The answer is 8 cm2.

Now the units must be squared because we are multiplying two numbers which makes it a 2D object.

### Example 2

Example 2:

For this example, the length is 14 cm and the width is 4 cm. To find the area of a rectangle, one way is to use the area formula which is Area = Length x Width. If we substitute the numbers into the equation, we will get Area = 14 cm x 4 cm. The answer is 56 cm2.

Now the units must be squared because we are multiplying two numbers which makes it a 2D object.

### Example 3

Example 3:

For this example, the length is 8 cm and the width is 4 cm. To find the area of a rectangle, one way is to use the area formula which is Area = Length x Width. If we substitute the numbers into the equation, we will get Area = 8 cm x 4 cm. The answer is 32 cm2.

Now the units must be squared because we are multiplying two numbers which makes it a 2D object.

### Example 4

Example 4:

For this example, the length is 13 cm and the width is 8 cm. To find the area of a rectangle, one way is to use the area formula which is Area = Length x Width. If we substitute the numbers into the equation, we will get Area = 13 cm x 8 cm. The answer is 104 cm2.

Now the units must be squared because we are multiplying two numbers which makes it a 2D object.
