Question

The area of a square is 800 meters, the length of each side is between what 2 numbers

a) 27 and 28
b)28 and 29
c)200 and 201
d)400 and 401

Answer 1

b

Explanation:

The area of a square = s² ← s is the length of the side, hence

s² = 800 ( take the square root of both sides )

s =
`√(800)` ≈ 28.28

28.28 is between 28 and 29 → b
