Question

if the area of a square is 64 sq unite what is the length of its side ?

Answer 1

As we know that,

Area of a square = length of side * length of side = l*l

So, 64=l²

     l= 8

So length of the side is 8 cm.

Answer 2

Answer:

Length of side of square is $8$ unit .

Step-by-step explanation:

To find : length of side of square .

Given : area of a square is 64 sq. units

Solution :

• We know that all four sides of square are equal .
• If ' $a$ ' is the side of square then area of square is given by,
• Area of square $= a^{2}$
• Therefore, by substituting the value in above formula we find length of side of square.

        $64 = a^{2} \\a = 8\ unit$
