Question

If the perimeter of an equilateral triangle is 36 inches what is the perimeter of it’s image under a dilation with a scale factor of 4

Answer 1

The perimeter of the image is 144 inches

so

The perimeter of the image is equal to the perimeter of the pre-image multiplied by the scale factor

`36(4)=144\ inches`
