Answer:

The width of the rectangle is 15 inches.

Explanation:

Take I as the length of the rectangle and w as its width. Use the relationship between the length and the width and express the length in terms of the width.


l = 1.5w

The perimeter of a shape is the sum of its sidelength, use this imformation to write a expression for the perimeter of the rectangle;


p = 2l \: + 2w

Now, replace l for the expression in terms of the width and P for the given perimeter, then solve for w:


75 = 2(1.5w) + 2w \\ 75 = 3 w + 2w \\ 75 = 5w \\ (75)/(5) = w \\ w = 15

The width of the rectangle is 15 inches.
