Answer: 19.62 * 10^7 cm

Step-by-step explanation:

  • Let a and b be rectangle sides.
  • Area = a * b
  • Perimeter = a + b + a + b = (a + b) * 2

a = 9.2 * 10^7 cm

Area = 5.612 * 10^14 cm^2

Find: Perimeter - ?

  • Area = a * b
  • b = Area / a

b = (5.612 * 10^14) / (9.2 * 10^7) = 0.61 * 10^7 cm

  • Perimeter = (a + b)*2

Perimeter = (9.2 * 10^7 + 0.61 * 10^7) * 2 = (9.2 + 0.61) * 10^7 * 2 = 9.81 * 2 * 10^7 = 19.62 * 10^7 cm
