A wire is in the shape of square of side 20 cm. If the wire is bent into a rectangle of length 24 cm, find its breadth.
Side of square = 20 cmPerimeter of square = 4 x 20 = 80 cmOr perimeter of rectangle = 80 cmLength of a rectangle = 24 cm∴ Perimeter of a rectangle = 2(l + b)b = 80/2 – 24b = 40 – 24 = 16 m
