If this was the case, there would be 3! ways.

3! = 3 × 2 × 1

   = 6 ways.

But one of the bracelets is chosen first. So, there are only 2 bracelets left to be interchanged.

∴ 2! = 2 × 1

       = 2

Step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
