Question

Look at this rectangle:
If both dimensions are tripled, then which of the following statements about its
perimeter will be true?
The ratio of the new perimeter to the old
perimeter will be 2:1
The ratio of the new perimeter to the old
perimeter will be 3:1.
The ratio of the new perimeter to the old
perimeter will be 1:2.
The ratio of the new perimeter to the old
perimeter will be 4:1.

Answer 1

Answer:

Step-by-step explanation:

If you multiply each side by 3, you can find out the answer by calculating it. The perimeter of the red figure is 2*L + 2*W = 2*7 + 2*4 = 14 + 8 = 22

Now let's triple the dimensions. The length of the new rectangle is 3*7 = 21

The width = 4*3 = 12

The perimeter = 2*12 + 2 * 21 = 24 + 42 = 66

What's the relationship?

It is 3 times larger so the ratio is 3:1 which is B
