Question

The side of a square is 2.5 cm. Find its perimeter and area.​

Answer 1

Perimeter = 10 cm

Area = 6.25 cm²

Explanation:

`\bf \: Given :`

`\sf \: Side \: of \: the \: square = 2.5 \: cm`

`\bf \: To \: find:`

`\rightarrow \sf \: Perimeter`

`\sf\rightarrow Area`

`\bf \: Solution :`

`\rm \: First \: w e \: need \: to \: find \: out \: the \: perimeter \: o f \: it.`

So to find the Perimeter of the square, we'll use this formula :

`\boxed{ \sf\longrightarrow \: Perimeter = 4 * side}`

`\bf \: Step \: 1 : \rm \: Put \: the \: value \: of \: side \: of \: the \: square :`

`\sf\longrightarrow \: Perimeter = (4 * 2.5)cm`

`\bf \: Step\;2 : \rm Multiply :`

`\sf\longrightarrow \: Perimeter = 10 \: cm`

Hence, the perimeter would be 10 cm .

`\rule{225pt}{2pt}`

`\sf \: Now,\; let's\; find \: the \: Area .`

We know that the formula of Area to find the square is,

`\boxed{ \sf \longrightarrow \: Area = (side) {}^(2) }`

Note : The answer would always be in cm².

`\bf Step\; 1 :\rm Put\; the\; value \; of\; side \; of \; the\; square :`

`\sf\longrightarrow{Area} = (2.5) {}^(2) \: cm {}^(2)`

`\sf\longrightarrow{Area} = (2.5 × 2.5 ) \: cm {}^(2)`

`\bf \: Step\;2 : \rm Multiply :`

`\longrightarrow\sf \: Area = 6.25 \: cm {}^(2)`

Hence, the area of the square would be 6.25 cm².

We are done !

`\rule{225pt}{2pt}`

I hope this helps!
