46 inches and 27 inches

=================

Let's denote the length of the rectangle as l and the width as w.

From the problem, we know that the perimeter of a rectangle is calculated as:

  • P = 2l + 2w

Since we are given the perimeter as 146 inches, we can form our first equation:

  • 2l + 2w = 146 or
  • l + w = 73

The problem states that the width is 4 inches more than one-half of its length.

This gives us our second equation:

  • w = (1/2)l + 4

Now, we can substitute the value of w from our second equation into our first equation:

  • l + (1/2)l + 4 = 73

Simplifying this equation, we get:

  • (3/2)*l + 4 = 73
  • (3/2)l = 69
  • 3l = 138
  • l = 46

Now that we have the length, we can substitute l into the second equation to solve for w:

  • w = (1/2)*46 + 4
  • w = 23 + 4
  • w = 27

So, the dimensions of the rectangle are:

  • length = 46 inches
  • width = 27 inches
