Step-by-step explanation: let's say the area=2. if you multiply by 2, it gets bigger. if d<1, it's like dividing by a number, meaning that the area becomes smaller.
1. If d is greater than one (d>1), then that means that the shape will be dilated outward, or expanded because the number is larger than the unit of 1.
2. Multiplying the coordinates by a fraction that is less than one (0<d<1) makes the shape smaller, because fractions are smaller than the unit of 1.
