Answer :
Final answer:
The total length of 66 extension cords, each 97 feet long, is estimated to be 6400 feet, corresponding to answer option (a).
Explanation:
The student is seeking to determine the total length of 66 extension cords, each measuring 97 feet in length. To estimate this, multiplication of the number of cords by the length of a single cord is necessary. By calculating 66 cords multiplied by 97 feet per cord, the product equals 6402 feet. For a better approximation, the closest option among the choices provided is 6400 feet, aligning with answer option (a).
Considering each extension cord's length of 97 feet and the quantity of 66 cords, the total length reaches 6402 feet. To find the most accurate estimation among the options, rounding off to 6400 feet is the closest match. Therefore, option (a) of 6400 feet serves as the better estimate for the combined length of the 66 extension cords.
