Answer:
When we write numbers in scientific notation, we must put the first non-zero digit ahead of the decimal. In this case, the decimal would be behind the 3. Because we moved the decimal places four times to the right, our exponent will be 4. Thus,
3.00 x 10⁻⁴

Step-by-step explanation:
2(l+w)=112.8
l+w=112.8/2
36.9+w=56.4
w=56.4-36.9
w=19.5
AD => Cos 20 = 12.6/H => H = 12.6/Cos 20 = 13.4cm
AB => √13.4^2 - 12.6^2 = 4.6 cm
BC = √19.3^2 - 12.6^2 = 14.6 cm
AC = 14.6 + 4.6 = 19.2 cm
