Here is how to find the answer for this problem. We know that the formula for getting the area of the rectangle is A = Length x Width. Given that the area is 37.5 inches squared and the length is 15 inches, let us just plug in the values. Let w be width. 35.7 in^2 = 15 in x w Next, we divide both sides by 15 and this is the result w = 2.5 inches. Therefore, the answer would be 2.5 inches. Hope this answer helps.
