Question

The rectangle shown is to be dilated by a scale factor of 3.5.

(a) Calculate the length of each side of the dilated image. Show your calculations for each side length.
(b) Draw the new image and label it
A B D C     . (It does not have to be to scale) .


The rectangle shows two sides being 18 cm and the other two being 8 cm

Answer 1

The answer to your problem is:

AB= 30cm

BD= 16cm

Explanation:

Since the one shown is to be dilated by a factor of 2, our new dimensions are 2x / 2y. We multiply each side length by two to get our new dilated image.

Which the side lengths being:

AB= 30cm

BD= 16cm

Thus the answer to the problem is:

AB= 30cm

BD= 16cm
