Murljashka [212]

Answer: 6 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 the carpet has been reduced.

<em>Original width of carpet x scale factor = 12</em>

<em>Dividing both sides by 8 feet we will get:</em>

<u><em>8 feet x Scale factor/8 ft = 2/8 ft</em></u>

<em>Scale Factor = 1/4 </em>

<em>Let us find the length of carpet after reduced by a scale factor of 1/4. </em>

Length of the carpet after reducing a factor of 1/4=12 ft x 1/4

Length of the carpet after reducing a factor of 1/4=3 ft.

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

Area of reduced carpet = 2 ft x 3 ft

Area of reduced carpet = 6 ft

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