Sonu is hanging a square picture frame with an area of \$144 cm^2\$. Find the side length of the frame.

$Test$

Step: 1

Given that the Area(a) is 144 sq.cm

The formula for the area of the square is: Area(a) = side(s) x side(s)

We need to determine the side(s) by using the formula 144 = s × s.

The square root of both sides of the equation to isolate the side length: 144 = \$s^2\$.

Explanation:

The area (a) is given as 144 square centimeters.
The formula for square area: Area (A) = side (s) x side (s).

Step: 2

To find the side (s) length and apply the square root on both sides:
\$\sqrt "144"\$ = \$\sqrt s^2\$
After the calculation, the side is 12 cm.

Explanation:

The length of one side after the calculation is 12 cm.
