2a= 2√2 + √(8-4*2) = 2√2 
hence, perimeter = 4a = 2*2a=2*2√2 = 4√2

borishaifa [10]

Answer:

  • 25 quarters
  • 13 dimes

Step-by-step explanation:

If you subtract the extra 12 quarters from the total, you have $4.55 that can be made up of groups of 1 quarter and 1 dime. Since those groups are worth $0.35, there are $4.55/$0.35 = 13 of them.

There are 13 dimes and 13+12 = 25 quarters in the purse.
