Find the length of a rectangle whose area is 120 square centimeters, and the width is 8 cm.

Answer :

To find the length of a rectangle given its area and one of its dimensions (in this case, the width), you can use the formula for the area of a rectangle:

[tex]\[ \text{Area} = \text{Length} \times \text{Width} \][/tex]

In the problem, you're provided with:

- The area of the rectangle: 120 square centimeters
- The length of the rectangle: 8 centimeters

We need to calculate the width. To do this, rearrange the formula to solve for the width:

[tex]\[ \text{Width} = \frac{\text{Area}}{\text{Length}} \][/tex]

Substitute in the given numbers:

[tex]\[ \text{Width} = \frac{120 \text{ cm}^2}{8 \text{ cm}} \][/tex]

[tex]\[ \text{Width} = 15 \text{ cm} \][/tex]

So, the width of the rectangle is 15 centimeters.
