Question

A rectangle has a perimeter of 15 inches. The image is created with a scale factor of 30%. What is the new perimeter? inches

Answer 1

We can write the scale factor in decimal form:

`30\%=(30)/(100)=(3)/(10)`

Then, since the image is created with a scale factor of 3/10, the new perimeter is:

`(3)/(10)(15)=(3\cdot15)/(10)=(45)/(10)=4.5`

therefore, the new perimeter is 4.5 inches
