Question

Six identical circles are arranged,as shown in the figure. The circles touch the sides of a large rectangle as well as each other. The vertices of the small rectangle coincide with the centres of four of the circles. The perimeter of the small rectangle is 60 cm.What is the perimeter of the large rectangle?

Answer 2

Figure?

Answer 3

is there a figure...go figure

Answer 4

Can you figure out the diameter of each circle?

Answer 5

ok... the the perimeter of the small recatangle is 60

so let d be the diameter of the circles..

so 2d in the length of the small reactangle and 1 d is the width.

so

60 = 2d + 2d + d + d

solve for d

now the large reactangle has length 3d

and width 2d

so

P = 3d + 3d + 2d + 2d

P = 10d

hope this helps.
