Answer 1

Answer:

The new width is 20

Step-by-step explanation:

w = 45

h = 27

We want the height to be 12

We can use proportions to find the new dimensions

w        w old      w new

----- = ---------- = ----------

h         h old        h new

45           w new

---------- = ----------

27            12

Using cross products

45*12 = 27 * w new

540 = 27 w new

Divide by 27

540/27 = 27 w new/27

20 = w new

The new width is 20

Answer 2

Answer:

7 1/5 cm

Step-by-step explanation:

45/27 = 12/x

x = 12*27 / 45

x = 324/45

x = 7 9/45

= 7 1/5
