Let the length = L and the width = W

Given : L = 24 + W and
2L+2W=240

Now, solve for L and W using algebra ...

Explanation:

Using substitution ...

2L+2W=240

2(24+W)+2W=240

Simplify and solve for W ...

48+4W=240

4W=192

W=48

Now, solve for L ...

L = 24 + W=24+48=72

In summary,

L=72 and W=48

hope that helped!
