Question

Suppose that an owner of the same dog breed has also taken some measurements. They notice that the surface area of the dog has increased by a factor of 3 over a period of four years. Determine the change in the dog's relative surface area in this time period.

Answer 1

Answer:

Surface area of the dog is changes from A to 3A

Explanation:

It is given that surface area of dog is increased by factor 3 in a period of 4 year

We have to find the change in dog's relative surface area in the given time period

Let initially the surface area is A

As the surface area is increased by a factor of 3

So surface area after 4 year = 3×A = 3A

So surface area of the dog is changes from A to 3A
