Lincoln School is having a fundraising contest. Each student is to design a school poster. The designs are to be made to fit a rectangle that is 12 cm by 16 cm and then dilated by a scale factor of 3. What will be the perimter and area of the final poster?
the perimeter will also grow by a factor of 3, so it will be
3*2(12+16) cm
the area will grow by a factor of 3^2, so it will be
3^2 (12*16) cm^2
