#1.40.02

#2.24.02

Step-by-step explanation:

#1.A=a2+2aa2

4+h2=42+2·4·42

4+2.242≈40.02346

#2.AL=aa2+4h2=4·42+4·2.242≈24.02346

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
