Question

24 squares of side length 1 cm are joined (edge to edge) to form a rectangle. What can be the least and the greatest perimeter of the rectangle formed?​

Answer 1

Hi,

Explanation:

The rectangle with the greatest perimeter is 24 by 1 :

perimeter=2*(1+24)=50

The rectangle having the least perimeter is the rectangle closest to the square. ( 6 by 4)

perimeter = 2(6+4)=20
