Answer: A Scale factor is a number which multiplies or scales a number in an equation.
Perimeter ratio is the ratio of the perimeter to the area.
Area ratio is the ratio of the total amount of usable floor a land has
Explanation:
Scale ratio can be established by this simple equation y=CX where C is the scale factor.
Perimeter ratio; perimeter = 2(L+B) where L is length and B is breadth
Area = L×B
Therefore perimeter ratio = 2(L+B)/L×B
Area ratio; L2 ×W2/L1×W1 where L1 and L2 are the lengths and W1 and W2 are the widths.
