L x l=20; 4l x l=20; 4l(at power of 2)=20; l=+/- square root of 5

If X equals the width, and the length is 4 times longer than the width then the length is 4x, there are 4 sides to a rectangle 2 widths of 1x and 2 lengths of 4 x for a total of 10 x 20cm divided by 10 equals x as 2 so the rectangle is 2cm wide and 8cm long! why don't you finish the problems and tell us the answer in CMs
