Answer:
the width of the rectangle is 5.
Explanation:
Let's assume that the width of the rectangle is x. Then, according to the problem statement, the length of the rectangle would be 3x.
The area of a rectangle is given by the formula:
Area = Length x Width
Substituting the values of length and width in the formula, we get:
75 = (3x) x (x)
Simplifying the right-hand side, we get:
75 = 3x^2
Dividing both sides by 3, we get:
25 = x^2
Taking the square root of both sides, we get:
x = ±5
Since the width cannot be negative, we take the positive value of x, which is 5.
Therefore, the width of the rectangle is 5
