Question

the area of a square field is 144m,find its area​

Answer 1

Answer:

if area is 144m2 then each side is 12m

Answer 2

NOTE :- Mistake in question .

$\bf{\underline{\underline{Question:-}}}$

• The Perimeter of a square field is 144m,find its area

$\bf{\underline{\underline{Solution:-}}}$

• Perimeter = 144m
• Side = Perimeter ÷ 4

So,

$\sf :→ 4 × side = perimeter$

$\sf :→ Side = \dfrac{Perimeter}{4}$

$\sf :→ Side = 36m$

Now,

• Area of square field = (side)²

$\sf :→ Area = 36^2$

$\sf :→ Area = 1296m^2$

$\bf{\underline{\underline{Hence:-}}}$

• The area of square is 1296m²

$\bf{\underline{\underline{Question:-}}}$

The area of the square is 144 sq. m. What is the length of its side.

$\bf{\underline{\underline{Solution:-}}}$

• Area of the square = Side x Side (formula)

• Area = 144 sq.m

$\sf :→ (Side)^2= 144 \:( given)$

$\sf :→ Side = \sqrt{144}$

$\sf :→ Side = \sqrt{12×12}$

:→ Side = ± 12

• Neglecting negative sign

:→ side is 12 m

$\bf{\underline{\underline{Hence:-}}}$

• Length of its side = 12m
