Question

Find area and perimeter of a square Whose side is 10cm​

Answer 1

$\LARGE{ \underline{\underline{ \pink{ \bf{Required \: answer:}}}}}$

Given:

Side = 10cm

Find:

Area = 10 x 10

= 100cm²

Perimeter = 4 x 10

= 40cm

Answer 2

Correct Question : Find the Area and perimeter of a square whose side is 10 cm.

Given : 10 cm

To Find : Area and perimeter of square.

Concept : Here we are given perimeter and Area.So,In this question we have to find the area and perimeter of square.So,let's solve!

⠀⠀⠀⠀⠀⠀⠀⠀____________________________

Firstly, we will find the Area of square!

Area :

We know that,

Area of square = a²

⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 10²

⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 100 cm

$.\dot \ .$ ${\underline{\textsf{Hence,Area \ of \ square is {\textbf{100 cm}}}}}$.

Now, we will find the Perimeter of square!

Perimeter :

We know that,

Perimeter of square = 4a

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 4 × 10

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 40 cm.

$.\dot \ .$ ${\underline{\textsf{Hence,Perimeter \ of \ square is {\textbf{40 cm}}}}}$.
