a table top is rectangular. the table's length is 60 cm more than its width. the perimeter of the table is 240 cm.

Dear Travina,

1. We know that the table's length, L, is 60 cm greater than its width, W.

2. We know that the perimeter, P, is 240 cm.

The equation is very simple:

P = 2*L + 2*W

But we already know that L = W + 60 cm

So rewrite the equation for the perimeter as:

P =2*(W + 60 cm) + 2*W

P = 240 cm = 2*W + 120 cm + 2*W

4*W = 240 cm - 120 cm = 120 cm

Therefore W = 30 cm.

So, the rectangular table has a length, L, of 90 cm and a width, W, of 30 cm.

Let's check our answer:

P = 2*L + 2*W = 2*(90 cm) + 2*(30 cm) = 180 cm + 60 cm = 240 cm.
