The length of a rectangle is 4 meters less than three times its width. If the perimeter of the rectangle is 48 meters, then what is the value of the length (in meters)?

Respuesta :

Answer:

7

Step-by-step explanation:

Think about it visually. 3x-4 is the length and x is the width. Since a rectangle has 2 parralel and equal sides, it's just double those. The equation is 8x-8=48. 48 is the total as given in the problem.

8x-8=48

8x=56

x=7

The width is 7
