The question I was given for 2.4 was #21:
"A baseball diamond is a square area of about 750 m². What is the distance from first base to second base? Give your answer to the nearest tenth of a metre."
I knew that the distance between first base to second base is also equal to the side length of the baseball diamond. Since 750 m² is the area, all I needed to do was find the square root of 750m²
For the answer, I got 27.3861279 m.
I had to round it to the nearest tenth, and since .08 is greater than .05, I changed 27.3 to 27.4 m.
The distance from first base to second base is 27.4 m.
