The answer is the first option, 28.6 m^2.
First, you know that the area of the square is 4 × 4 = 16 m^2.
The area of a regular circle is π × radius^2, but for a quarter circle, that changes to (π × radius^2)/4. We use 3.14 as π, and 4 is the radius, so we get (3.14 × 4^2)/4 = 50.24/4 = 12.56. Now we just need to add this to our original 16 m^2 to get the answer of 28.56, which rounds to 28.6 m^2. I hope this helps!
Ok so here first lets find out how much that it would cost Rico to buy 5 notebooks, to find this first we need to find the unit price of each of these, this can be found by taking the price divided by the amount that they bought or are selling to you. So we take 7/4=1.75 then 2.5/10=.25, so we now know that it costs $1.75 for one notebook and $0.25 for one folder. Now to find are end answer just multiply these unit prices by the amount that he needs like this, 1.75*5=8.75, and .25*6=1.5. So are end answer is that it will cost Rico $8.75 for 5 notebooks and $1.50 for 6 folders, or 8.75+1.5=10.25, so it will cost him in total $10.25 for 5 notebooks and 6 folders.

hope this helps! good luck. :)
Given is the borrowed amount = 380 dollars.
Repayment period = 6 months.
Monthly installments = 67 dollars.
After six months, total repaid amount would be sum of all six monthly installments i.e. 6 x 67 = 402 dollars.
The interest to be paid on this loan would be difference of total repaid amount and borrowed amount.
Interest paid = Repaid amount - Borrowed amount
Interest = 402 dollars - 380 dollars
Interest = 22 dollars.
So, he would pay 22 dollars as interest on this loan.
