The length of a rectangle is 5 cm greater than it width. The perimeter is 58 cm. What are the dimension of the rectangle?

I know the formula for Triangle Perimeter is 2(L+W) and the L is +5 more than the W but I can't write the equation for it. This is what I was thinking 58= 4x-5

Thanks again.

2(x+(x+5))=58

2(2x+5)=58

4x+10=58

then subtract 10 from both side, which gives you,

4x=48

here x=12 and the length is x+5 which is 12+5=17

L:17 and B:12

perimeter=2(l+W)=2(w+5+w)
