Answer:

area=320m²

Step-by-step explanation:

perimeter=2(l+w)

72=2(l+16)

72/2=l+16

36=l+16

36-16=l

l=20m

area=l*w

=20*16

=320m²

$1000 invested with compound interest at a rate of 15% per year for 9 years. Formula: M = P(1+ i)n Group of answer choices $3517

BaLLatris [955]

Answer:

Option A.

Step-by-step explanation:

Note: Let as consider, we have to find the total amount after 9 years.

It is given that,

Principal amount = $1000

Rate of compound (yearly) interest = 15% = 0.15

Time = 9 year

The formula for total amount is

$M=P(1+i)^n$

where, P is principal, i is rate of interest and n is number of years.

Substituting P=1000, i=0.15 and n=9, we get

$M=1000(1+0.15)^9$

$M=1000(1.15)^9$

$M=1000(3.5178763)$

$M=3517.8763$

$M\approx 3517.88$

So, the total amount after 9 years is $3517.88.

Therefore, the correct option is A.
