Rectangle qqq has an area of 222 square units. thea drew a scaled version of rectangle qqq and labeled it rectangle rrr. what scale factor did thea use to go from rectangle qqq to rectangle rrr?

Sagot :

The scale factor that thea used to go from rectangle q to rectangle r is; 6

How to work with Scale Factors?

The original rectangle q is missing and so I have attached it.

The length and width of the original rectangle as seen in the attached file are;

Length = 9

Width = 8

Thus;

Area of rectangle r = 9 * 8 = 72 sq.units

Since rectangle q has an area of 2 sq.units, then the area scale factor is;

72/2 = 36

Thus, scale factor in units = √36 = 6
