The perimeter of the 1st square is .
The perimeter of the 2nd square is
The perimeter of the 3rd square is
Continue in that way and sum the perimeters of the first five squares to find
Diagram shows the first four squares from a series of squares.The side of these squares decreases in a geometric progression.The side of the first square is cm and the side of the subsequent square is . cm
a)if the sum of the perimeters of the first five squares is . find the value of .
b)Hence,find the area of the square.
