Answer: B. The value of x is 625; The width is 25
Explanation:
We know that the area of a rectangle is length times width. Therefore, to find the width of the rectangle, you divided 75 by 3. As a result, we have 25. Now that we have the width, we have to find x. Because the inverse operation of a square root is to elevate the number to the power of 2, we must multiply 25 times 25. As a result, we get 625. If we plug it into the equation, it still makes sense. The square root of 625 is 25 and 25 times 3 is 75.
