What is the dimensions of a rectangle with a perimeter of 34 inches and an area of 42 inches squared?
The dimensions of the rectangle are 3 inches by 14 inches
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.
