Question

A rectangle has length of 80cm and a width 50cm. And a scale factor of 3.5 what is the area in square cm of the dilated rectangle

Answer 1

49,000 square cm

Explanation:

To get the area of the dilated rectangle, we need the dilated dimensions

We simply multiply the scale factor by the dimensions

we have this as;

3.5 * 50 = 175 cm

and

3.5 * 80 = 280 cm

The area of the dilated rectangle is thus;

280 * 175 = 49,000 cm^2
