A school has purchased a large field that has a square area of 19,500 ft2. What is the approximate length of each side of the square area? Round your answer to the nearest foot.

a.
140 ft
c.
142 ft
b.
139.64 ft
d.
139 ft

area=s^2

s=sqrt(area)=sqrt(19500)

To find the length of each side of the square field, we need to find the square root of the area.

The square root of 19,500 is approximately 139.64.

Rounding this to the nearest foot gives us a length of 140 feet.

Therefore, the approximate length of each side of the square area is 140 ft.

So the answer is option a. 140 ft.
