The equation which is used to determine x, the width of the window is,
. Option B shows the correct expression for width x of the window.
<h3>
What are length and width?</h3>
Length is describing how long is the object. The width is defined as how wide is the object.
Given that the width of the window is 4.9 feet. The length is given as 0.6 feet less than 2.5 times its width.
The height of the window is given as,

The other height of the window is given as,

When equating both equations, we get,

Therefore, an equation which is used to determine x, the width of the window is,
. Option B shows the correct expression for width x of the window.
