Triangle rst is the pre-image of triangle uvw with a scale factor of 3. find the area of triangle uvw if the area of triangle rst is 9 cm2.

We determine the area of the triangle UVW given that we have a scale factor of 3 by multiplying the area of triangle RST by the square of the scale factor. That is,
                                area of UVW = (9 cm²)(3²)
                                                      = 81 cm²
Thus, the area of triangle UVW is equal to 81 cm².

4038 is the answer lol just use a calculator
