Question

what is the side of square whose area is144sq.cm.

Answer 1

Answer:

$\boxed{12 \: cm}$

Given:

Area of square = 144 sq. cm

Step-by-step explanation:

Let the side of square be 'x'

$Area \: of \: square = {side}^{2} \\ \\ 144 = {x}^{2} \\ \\ {x}^{2} = 144 \\ \\ x = \sqrt{144} \\ \\ x = \sqrt{ {(12)}^{2} } \\ \\ x = {12}^{\cancel{2} \times \frac{1}{ \cancel{2}} } \\ \\ x = 12$

Additional information:

Area of triangle = $\frac{1}{2}$ × Base × Height

Area of rectangle = Length × Breadth

Area of circle = πr²

Area of trapezium = $\frac{1}{2}$ × Sum of parallel sides × Height

Area of parallelogram = Base × Vertical height

Answer 2

Area of square =(side)^2
=)144=(side)^2
=)side=root 144
Hence, side=12 cm
