Question

If five squares, each with sides equal to 4n, are divided into 4 equal squares as shown, what will be of the sum of the perimeters of the 20 smaller squares?

Answer 1

Side of a square = 4n

Side of the smaller square = 4n÷2 = 2n

Perimeter of one smaller square = 2n x 4 = 8n

Perimeter of 20 smaller squares = 8n x 20 = 160n

Answer: Perimeter of all the 20 smaller squares = 160n
