Question

The area of the square is \[36c{m^2}\]. How long is each side?
A.4cm
B.6cm
C.8cm
D.3cm

Answer 1

Hint: Given the area of a square is \[36c{m^2}\]. Now using the formula for finding the area of a square we can find the length of the side of that square. By taking the square root of the area we will get the length of the square.

Formula used:
Area of a square= \[{(side)^2}\]

Complete step-by-step answer:
Given the area of the square is \[36c{m^2}\].

Now let the length of the side be x.
Putting the values we get,
\[ \Rightarrow 36 = {\left( x \right)^2}\]
Taking the square root on both sides,
\[ \Rightarrow 6 = x\]
The length of the side of the square is 6cm.
Thus the correct option is B.

Note: When we find the area of a square we multiply the side of a square with its side. Or simply we take a square of the length of the side. Area can be defined as the space occupied by the shape.
