Question

Triangle A is dilated by a scale factor of 2. What is the ratio of the perimeter of Triangle A to the perimeter of Triangle B?

Answer 1

the answer is 2



good luck

Answer 2

the ratio is 1:2

Explanation:

Triangle A is dilated by a scale factor of 2

Suppose we take triangle A with sides a,b,c

To find the perimeter we add all the side. So the perimeter of triangle A is

`perimeter of A = a+b+c`

Triangle A is dilated by a scale factor of 2. So we multiply the sides of the triangle by 2. when we multiply the sides by 2 then sides becomes 2a,2b, 2c

Now the perimeter of triangle B is
`2a+2b+2c=2(a+b+c)`

So the perimeter of triangle B is 2 times the perimeter of triangle A

the ratio is 1:2
