The length of a rectangle is three times its width.

If the perimeter of the rectangle is
48cm,find its area.

no... don't know how to do it...

The width is 6 cm.

Length = 3 * 6 = 18 cm

A = L * W

A = 6 * 18 = ________ square cm.

it would be 108 square cm right??

Yes, you're right.

thx...

YW

48 = 2(3W + W)

48 = 8W

6 = W

Can you take it from there?
