Does it matter which dimensions you select for the length and width when you find the area of a rectangle?

not really but the length is always the longer side :)


The length of a rectangle is 4cm longer than the width if the perimeter of the rectangle is 20cm what is the area of the rectangle?

First find the dimensions of the rectangle. Let the length be x+4 and the width be x: 2(x+4+x) = 20 2x+8+2x = 20 4x = 20-8 4x = 12 => x = 3 Therefore: length = 7cm and the width = 3cm Area = length*width => 21cm2
