Polygon Y has an area of 11 square units. Celia drew a scaled version of polygon Y using a scale factor of 3 and labeled it polygon Z

99 square units

Step-by-step explanation:

We are given;

We are required to determine the area of polygon Z

We need to know that;

Area scale factor = Square of Linear scale factor

That is;

Area scale factor = 3²

       = 9

Hence;

Area of polygon Z = Area of polygon Y × Area scale factor

                              =  11 square units × 9

                             = 99 square units

Thus, the area of polygon Z is 99 square units
