Question

A piece of the spring is 30cm long what will be the length of each side a save the spring is used to form a square

Answer 1

Answer :

• Length of its side is 7.5m

Given :

• A piece of the spring is 30cm long

To find :

• Length of side

Solution :

We need to find a square,

Given that , The string is used to form a square so ,

• Length of string = Perimeter of square

As we know that,

• Perimeter of square = 4a

》 30 = 4a

》 4a = 30

》 a = 30/4

》 a = 15/2

》a = 7.5m

Hence , Length of side is 7.5m

More Explanation :

• Area of square s²
• Perimeter of square = 4a
• Square has 4 sides
• Square has 4 vertices
• All interior angles are equal to 90⁰
• Square is 2D

Answer 2

Given :-

• A piece of the spring is 30 cm long

To find :-

• Find the Length of the side ?

★ $\large\sf{\frak{As we know that,}}$

$\large\dag$ Formula Used :

• $\boxed{\bf{Perimeter~of~square~=~4a}}$$\large\star$

Solution :-

• The string is used to form a square
• Length of string = Perimeter of square

:$\implies$30 = 4a

$~~~~~$:$\implies$4a = 30

$~~~~~~~~~~$:$\implies$a = $\large{\sf{\frac{30}{4}}}$

$~~~~~~~~~~~~~~~$:$\implies$a = $\large{\sf{\frac{15}{2}}}$

$~~~~~~~~~~~~~~~~~~~~$:$\implies$a = ${\cancel{\dfrac{15}{2}}}$

$~~~~~~~~~~~~~~~~~~~~~~~~~$:$\implies$${\underline{\boxed{\pink{\frak{a~=~7.5~m}}}}}$★

$\large\dag$ Hence,

• The Length of the side is = $\large\underline{\rm{7.5~m}}$
