Find the amount of the principal when the simple interest rate is 4.345%, the time is 7 months, and the amount of interest earned is $274.00.

tis noteworthy that 7 months is not even a year, since there are 12 months in a year then 7 months is really 7/12 of a year.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
