A rectangle measures 4 inches by 10 inches. It is dilated using a scale factor of 2.5. What is the area in square inches of the dilated rectangle?(1 point) Responses 2,500 2,500 250 250 160 160 40

1 answer

To find the area of the dilated rectangle, we first need to determine the dimensions of the original rectangle and then apply the scale factor.

The original rectangle measures:

  • Length = 10 inches
  • Width = 4 inches

The area of the original rectangle is calculated as: \[ \text{Area} = \text{Length} \times \text{Width} = 10 , \text{inches} \times 4 , \text{inches} = 40 , \text{square inches} \]

Next, we dilate the rectangle using a scale factor of 2.5. The new dimensions will be:

  • New Length = \(10 , \text{inches} \times 2.5 = 25 , \text{inches}\)
  • New Width = \(4 , \text{inches} \times 2.5 = 10 , \text{inches}\)

Now, we can calculate the area of the dilated rectangle: \[ \text{Area of dilated rectangle} = \text{New Length} \times \text{New Width} = 25 , \text{inches} \times 10 , \text{inches} = 250 , \text{square inches} \]

Thus, the area of the dilated rectangle is \(250\) square inches.

The correct response is: 250.
