Question

Pls help me to solve this question with explanatio.
Given that the area of a piece of square tile is 49 cm2
, find its perimeter.

Answer 1

Solution

Given :-

• Area of Square = 49 cm²

Find :-

• Perimeter of Square

Explanation

Important Formula

★ Area of Square = (Side)²

★ Perimeter of Square = 4 * (Side)²

________________________

So,

➠ Area of Square = (Side)²

➠ 49 = (Side)²

➠ Side = ±√7

But, we know, length be always positive .

➠ Side = 7 cm

Now, Calculate Perimeter of Square

➠ Perimeter of Square = 4 * Side

➠ Perimeter of Square = 4 * 7

➠ Perimeter of Square = 28 cm

___________________

Hence

• Perimeter of Square be = 28 cm

Answer 2

★ Question ★

→ that the area of a piece of square tile is 49 cm2 find its perimeter.

$\rule{300}2$

→ Given

→ Area of square price tile is = $\bold49^2$

→ To find,

★ perimeter of the square = ?

$\rule{300}2$

★ Answer ★

→ Area of the square =$side^{2}$or $a^{2}$

→ $49= side^{2}$

→ $side= \sqrt49 \\ \longrightarrow side = ±7$

$\rule{300}2$

★ Perimeter = 4× side

→ Perimeter= 4×7

→ Perimeter = 28$cm^{2}$

$\rule{300}2$

◇ Formula which are used ◇

○ Area of square = $\huge side^{2}$

○ Perimeter of square = 4 × side
