The length of the side of a square with an area of 1600 m2 is __ metres.
If the side of the square is a, its area is a2.
According to question,
a2 = 1600 a2 = 2*2*2*2*10*10 a = √2∗2–––––∗2∗2–––––∗10∗10–––––––– ↓↓↓ 2∗2∗10 a = 40 m
The length of the side of a square with an area of 1600 m2 is __ metres. (Enter numerical value)
