Question

Arlene wants to create a scale drawing of the poster shown below: A rectangle is shown. The length of the rectangle is labeled 6 inches. The width of the rectangle is labeled 9 inches. What are the dimensions of the poster at one-third its current size?

Answer 1

1/3 of the dimensions means to divide the dimensions by 3. This is to figure out what 1/3 of the dimensions are.

Our length is 6, and our width is 9.

Let's divide our length first.

6/3 = 2.

Our length with 1/3 of it's original dimensions is 2.

Let's divide our width now.

9/3 = 3.

Our width with 1/3 of it's original dimensions is 3.

Our dimensions are 2 by 3.

Your answer is A.) 2 in. by 3 in.

Explanation:

Answer 2

If you divide each of the lengths by 3, thus giving you the one-third of the finishing size, you'll get 2 inches for the length and 3 inches for the width.
If dimensions is perimeter, you get 2+2+3+3=10
10 inches=Perimeter.

You could also add up the sides and divide them by 3.
6+6+9+9=30
30/3=10 inches
