Answer 1

South Dakota is 37.7 times larger than Puerto Rico.

Using the parameters given for our Calculation;

• South Dakota = 2×10⁵ km²
• Puerto Rico = 5.3×10³ km²

To calculate the number of times South Dakota is larger than Puerto Rico, we divide ;

• South Dakota / North Dakota

Now we have :

2×10⁵ = 200000

5.3×10³ = 5300

Evaluating:

200000 / 5300 = 37.7358

Rounding to the nearest tenth : 37.7

Hence, South Dakota is 37.7 times larger than Puerto Rico.
