statuscvo [17]

Answer:

$\text{Area of reduced carpet}=6\text{ ft}^2$

Step-by-step explanation:

We have been given that a piece of carpet is 8 feet wide and 12 feet long. The carpet needs to be reduced by a scale factor so that the reduced carpet is 2 feet wide.

First of all, let us find the scale factor by which the width of carpet has been reduced.

$\text{Original width of carpet}\times \text{Scale factor}=2\text{ ft}$

$\text{8 ft}\times \text{Scale factor}=2\text{ ft}$

Dividing both sides by 8 ft we will get,

$\frac{\text{8 ft}\times \text{Scale factor}}{\text{8 ft}}=\frac{2\text{ ft}}{\text{8 ft}}$

$\text{Scale factor}=\frac{1}{4}$

Let us find the length of carpet after reduced by a scale factor of $\frac{1}{4}$ .

$\text{Length of the carpet after reducing a factor of }\frac{1}{4}=12\text{ ft}\times \frac{1}{4}$

$\text{Length of the carpet after reducing a factor of }\frac{1}{4}=3\text{ ft}$

Now we will multiply the reduced length and width of carpet to find the area of reduced carpet.

$\text{Area of reduced carpet}=2\text{ ft}\times 3\text{ ft}$

$\text{Area of reduced carpet}=6\text{ ft}^2$

Therefore, the area of reduced carpet is 6 square feet.
