Answer 2

A square lot has an area of 1,200 square meters. To the nearest meter, how far is it from one corner to the opposite corner?

Possible Answers:

49 meters

25 meters

98 meters

300 meters

196 meters

Correct answer:

49 meters

Explanation:

A square is also a rhombus, so its area can be calculated as one half the product of its diagonals:

A=12d2,

where d is the common diagonal length.

Since A=1200, 1200=12d2.

2400=d2

d=2400−−−−√≈49

The distance between opposite corners is about 49 meters.
