Question

A rectangular picture window 12-feet long and 6-feet wide needs to be shortened to 9 feet in length to fit in a redesigned wall. If the architect wants the new window to be similar to the old window, how wide will the new window be?

Answer 1

12 6__ = __ 9 w
12w = 6 x 9 = 54 w = 54 divided by 12 w = 4.5

Answer 2

To find the desired width we need to solve the equation:

`(9)/(12)=(x)/(6)`

`(3)/(4)=(x)/(6)`

`x=(3*6)/(4)=(18)/(4)=(9)/(2)=4.5`

So, the new window will be 4.5 feet wide.
