Answer:

39 cm

Step-by-step explanation:

The perimeter of a rectangle is given as 2 (w + l) or 2w + 2l, where w and l are the sides.

Let us use w as 3 cm.

The perimeter of the rectangle is 2(3) + 2l = 6 + 2l

6 + 2l = 84 cm

We move the 6 to the left hand side and it goes from positive to negative.

2l = 84 - 6cm

2l = 78 cm

Divide both sides by 2.

l = 39 cm

There you have the answer for side l.
