Using this formula l=A 1/2 what is the length of one side of a square with an area of 1,936 square kilometers? (A is the area of a square.)
a.)11 kilometers
b.)22kilometers
c.)44 kilometers
d.)968 kilometers

Respuesta :

msm555

c.)44 kilometers

Answer:

Solution given:

let

length =L

and

Area =A

Now

we have

Area [A]=1936 square kilometers

now

As we know that

Area of square :length *length

A=l*l

A=l²

Substituting value of A

1936=l²

doing square root on both side

[tex]\sqrt{1936}=\sqrt{l²}[/tex]

we get

l=[tex]\sqrt{2*2*2*2*11*11}[/tex]

l=2*2*11

l=44 kilometers

So

the length of one side of a square is 44 kilometers.
