Question

If the area of a square plot is $676{\text{m}}^2$, then the side of the square plot is _____

• A. 28 m
• B. 26 m
• C. 24 m
• D. 34

Answer 1

The correct option is B

26 m

Let the sides of square be ${}^{\prime }{a}^{\prime }$

Area of square is $a^2$

$\therefore a^2=676$

$\Rightarrow a=\sqrt{676}$

$\Rightarrow a=\sqrt{2\times 2\times 13\times 13}$

$\Rightarrow a=2\times 13$

$\Rightarrow a=26\text{m}$
