Interpret the given measures as L = 9.3×10^2 = 930 cm and W = 8.1×10^1 = 81 cm.
1) Area = L×W = 930×81 = 75,330 = 7.533×10^4 cm^2 → True.
2) Perimeter = 2(L+W) = 2(930+81) = 2(1,011) = 2,022 = 2.022×10^3 cm → False (not 1.71×10^3).
3) Ratio L/W = 930/81 ≈ 11.481 ≈ 1.15×10^1 → True.
4) L^2 = 930^2 = 864,900 ≈ 8.649×10^5 ≈ 8.65×10^5 → True.
