Question

Ivory created a scaled copy of triangle C using a scale factor of 4.

What is the height of Ivory's copy?

Answer 1

Height of the Ivory's copy = 12 units

Explanation:

Formula to get the scaled copy of any figure is,

Scale factor =
`\frac{\text{Dimensions of the image triangle}}{\text{Dimensions of the original triangle}}`

For triangle C,

Scale factor for the image created = 4

Height of triangle C = 3 units (From the figure attached)

By substituting these values in he formula,

4 =
`\frac{\text{Height of the image triangle}}{3}`

Height of the image triangle = 4 × 3 = 12 units

Therefore, height of the Ivory's copy will be 12 units.
