Question

Consider $2$ squares $A$ and $B$ with the area $25c{m}^2$ and $49c{m}^2$ respectively. Find length of their sides and then determine which square has smaller side length.

• A. $A$
• B. $B$
• C. Both are same
• D. Can't be determined

Answer 1

Answer: (A)

$A$

Area of square$A=25㎠$

$\therefore$Side of square $A=\sqrt{25}=5㎝$

Area of square $B=49㎠$

$\therefore$Side of square $B=\sqrt{49}=7㎝$

Therefore side of square $A$ is less than of square $B$.
