The expression 4 · √81 gives the perimeter of the square shown. What is the perimeter, in meters, of the square?
A) 16 m
B) 24 m
C) 36 m
D) 48 m
To find the perimeter of the square, we first evaluate the expression ( 4 cdot sqrt{81} ).
1. Calculate ( sqrt{81} ):
[ sqrt{81} = 9 ]
2. Now, substitute this value back into the expression:
[ 4 cdot 9 = 36 ]
Thus, the perimeter of the square is 36 meters.
The correct answer is C) 36 m.
To find the perimeter of the square using the expression (4 cdot sqrt{81}), we first need to calculate (sqrt{81}).
1. Calculate (sqrt{81}):
[
sqrt{81} = 9
]
2. Now, multiply by 4:
[
4 cdot 9 = 36
]
Thus, the perimeter of the square is 36 meters.
The correct answer is C) 36 m.
