5 inches = 7 feet
21/7 = 3, 3*5 = 15 inches
28/7 = 4, 4 *5 = 20 inches
3rd answer 15 inches by 20 inches

Answer:
4 and 10
Step-by-step explanation:
1) Quaterly interes = 3% / 4 = 0.03 / 4
2) Values:
after 1 quarter: 2000 (1 + 0.03/4)
after 2 quarters: 2000 (1 + 0.03/4)^2
after 3 quarters: 2000 (1 + 0.03/40^4
after 4 quarters = 2000 (1 + 0.03/4)^4
You could have used the future value formula directly:
A = C * (1 + r/n) ^ n*t
where r = 3% = 0.03
n = number of periods in a year: 4
t = number of years = 1
C = initial investment = 20000
=> A = 2000 (1 + 0.03/4)^4
Answer: option D. A = 2000 ( 1 + 0.03 /4) 4
