Answer:

a. 4/5

b. 150 and 120

Step-by-step explanation:

To find the scale factor first find two sides that correspond and have measurements. This is the length of each rectangles which are 50 and 40.

The equation for scale factor when scaling down is

SF = Smaller Length / Longer Length

When scaling up it is

SF = Longer / Smaller

We are scaling down so we plug in our numbers.

SF = 40 / 50

Solve for SF = .8 or 4/5.

For permimiter you add all four sides. Multiply the width of the larger pool by the scale factor. 25*.8 = 20

20 + 20 + 40 + 40 = 120

25 + 25 + 50 + 50 = 150
