Question

the perimeter of a rectangle is 524cm. the length is 42 cm more than the width. what is the length of the rectangle

Answer 1

The length is 152 centimeters.

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!
