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?
Accepted Solution
A:
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 ------------------------------------------------------------------------------
