Option D is the correct answer

2w+2.(3w)\leq 112

Further explanation:

Let

l\ be\ the\ length\ of\ rectangle\\and\\w\ be\ the\ width\ of\ rectangle

The perimeter of a rectangle is given by:

P=2w+2l

It is also given that:

P\leq 112

So we can write as

2l+2w\leq 112

We also know that The length of the rectangle is three times its width

l=3w

Putting the value of l in the inequality

2.(3w)+2w\leq 112

Rearranging the terms

2w+2.(3w)\leq 112

Hence, option D is the correct answer.
