Answer:

163125

Step-by-step explanation:

Divide the numbers then divide the exponents. Put them back together once done.

\frac{5.22}{3.2} = 1.63125

\frac{10^{9}}{10^{4}} =10^{5}

To get 163125, I moved the decimal point 5 places to the right since the exponent is 5.

1.63125*10^{5}=163125

  A = LW

  W = A/L = (29.76 m²)/(6.2 m) = 4.8 m
