Best Answer

A rectangle has two dimensions, length and width. You haven't said what the width is.

The perimeter is the distance around the rectangle. Imagine going round it. You would go 42 inches, then a width, then another 42 inches, then another width.

In general, the perimeter of a rectangle is twice its length plus twice its width.
