Final answer:
To find the value of x given the perimeter of a rectangle, we can use the formula P = 2L + 2W and solve for x. However, without knowing any other information about the rectangle, such as the length or width, it is not possible to determine the value of x.
Step-by-step explanation:
To find the value of x, we need to use the formula for the perimeter of a rectangle, which is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width. In this case, we know that the perimeter is 7 3/5 units. So we can set up the equation 7 3/5 = 2L + 2W and solve for x. Now, we need to know if any other information is given about the rectangle, such as the length or width. Without that information, it is not possible to determine the value of x.
