Answer 2

Given:

एक वर्गाकार बोर्ड का क्षेत्रफल 144 वर्ग इकाई है।

To find:

इसकी एक भुजा की माप बताइए?

Solution:

The area of a square-shaped board = 144 sq. units

We know,

$\boxed{\bold{Area \:of\:a\:square = side^2}}$

Let "a" represents each side of the square-shaped board.

Therefore, by using the formula, we get

$a^2 = 144$

$\implies a = \sqrt{144}$

since 12² = 144

$\implies a =$ ± $12$

since the measurement of the board cannot be in negative

∴ $\bold{a = 12\:units}$

Thus, the length of each side of the board is → 12 units.
