To solve this problem, you can set up a proportion using the given information.
Let's represent the original width as W and the original height as H. According to the problem, the original width is 24 inches and the original height is 12 inches.
Now, the new height (after Shawna reduces the size) is given as 2 inches. Let's represent the new width as X.
We can set up the proportion:
Original Width / Original Height = New Width / New Height
Substituting the given values:
24 in / 12 in = X / 2 in
Simplifying the proportion:
2 = X / 2
To solve for X, we can cross-multiply by multiplying both sides of the equation by 2:
2 * 2 = X
4 = X
Therefore, the new width is 4 inches.
So, to solve it and obtain an answer of 4, you set up a proportion by dividing the original width by the original height, which equals the new width divided by the new height. Then, you cross-multiply and solve for the unknown variable, X, which represents the new width.
