the perimeter of a parallelogram can be written as P= 2(a+b), where a and b are the lengths of the sides of the parallelogram. since the parallelogram has been dilated by a scale factor of 0.6, we multiple the original side lengths by 0.6. 12 × 0.6 = 7.2 16 × 0.6 = 9.6 Plug into the equation P=2(7.2+9.6) P=2(16.8)
P= 33.6
You can also solve by plugging in the original values and multiplying the answer by 0.6. P=2(12+16)(0.6) P=2(28)(0.6) P=(56)(0.6)
