<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The length of a picture is 18.25 inches shorter than twice the width. Therefore,
L = 2W - 18.25 inches
If the perimeter of the picture is 119.5 inches, therefore, the perimeter of the picture is,
Perimeter = 2(L+W)
119.5 = 2(2W - 18.25 + W)
119.5 = 2(3W-18.25)
119.5 = 6W - 36.5
156 = 6W
W = 26
Now, the length of the picture will be,
L = 2W - 18.25
L = 2(26) - 18.25
L = 33.75 inches
Hence, the length and the width of the picture are 33.75 inches and 26 inches, respectively.
