following measures is closest to the length of one of its sides?
11.8 cm
B

C 12.7 cm
D
13.5 cm

Answer 1

Answer:

C) 12.2 cm

Step-by-step explanation:

To find the area of a square, you multiply length and width, which for a square, are the same. So to find the length of one of its sides, you have to take the square root of the area.

$L^{2} = 150\\\\L=\sqrt{150} \\L= 12.2$
