Answer:
The length is 152 centimeters.
Step-by-step explanation:
Since the perimeter of a rectangle is the width plus the length multiplied by 2, you can set up a simple system of equations to solve this problem.
2l+2w=524
l=w+42
Now, you can substitute this back into the first equation:
2(w+42)+2w=524
4w+84=524
w=110
l=152
Hope this helps!
