A rectangle with an area of 8 ft² is dilated by a factor of 4. What is the area of the dilated rectangle?
prohojiy [21]

Answer:

Option 4) 128\ ft^{2}

Step-by-step explanation:

we know that

If two figures are similar then the ratio of its areas is equal to the scale factor squared

Let

z------> the scale factor

x-----> the area of the dilated rectangle

y----> the area of the original rectangle

so

z^{2}=\frac{x}{y}

we have

z=4

y=8\ ft^{2}

substitute and solve for x

4^{2}=\frac{x}{8}

x=16(8)=128\ ft^{2}
