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
Vera_Pavlovna [14]

<u>c.)44 kilometers</u>

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

\sqrt{1936}=\sqrt{l²}

we get

l=\sqrt{2*2*2*2*11*11}

l=2*2*11

l=44 kilometers

So

<u>the length of one side of a </u><u>square</u><u> </u><u>is</u><u> </u><u>4</u><u>4</u><u> </u><u>kilometers</u><u>.</u><u />
