Question

help me by answering this question.

really it's very urgent
answer it by whole explanation.

answer both the question (a &b) ​

Answer 1

$\Large{\bf{\green{\mathfrak{\dag{\underline{\underline{Given:-}}}}}}}$

• Area of 2 squares =

• (a) 225 m²

• (b) 81 mm²

$\Large{\bf{\orange{\mathfrak{\dag{\underline{\underline{To \: Find:-}}}}}}}$

• Length of side of Squares.

$\Large{\bf{\red{\mathfrak{\dag{\underline{\underline{Solution:-}}}}}}}$

We know that,

$\boxed{\pink{\sf Area \: of \: a \: Square \: = \: s^2 \: units^2}}$

(a) :-

• Here,

• Area of Square = 225 m²

Substituting the values,

• 225 m² = s²

• s = $\sf \sqrt{225}$

• s = 15 m

(b) :-

• Here,

• Area of Square = 81 m²

Substituting the values,

• 81 mm² = s²

• s = $\sf \sqrt{81}$

• s = 9 mm

Therefore,

$\boxed{\purple{\textsf{Length of side of Square [(a) 225 m²] = 15m.}}}$

$\boxed{\blue{\textsf{Length of side of Square [(b) 81 mm²] = 9mm.}}}$

Answer 2

Answer:

Given :-

• (a) Area = 225 sq.m
• (b) Area = 81 sq.mm

To Find :-

• What is the length of the side.

Formula Used :-

$\clubsuit$ Area of Square Formula :-

$\longmapsto \sf\boxed{\bold{\pink{Area\: Of\: Square =\: {(side)}^{2}}}}$

Solution :-

${\small{\bold{\purple{\underline{\bigstar\: (a)\: Area\: =\: 225\: sq.m}}}}}$

Given :

• Area of Square = 225 m²

According to the question by using the formula we get,

$\implies \sf {(side)}^{2} =\: 225$

$\implies \sf side =\: \sqrt{225}$

$\implies \sf side =\: 15$

$\implies \sf\bold{\red{side =\: 15\: m}}$

$\therefore$ The length of the side is 15 m .

$\rule{150}{2}$

${\small{\bold{\purple{\underline{\bigstar\: (b)\: Area\: =\: 81\: sq.mm}}}}}$

Given :

• Area of Square = 81 mm²

According to the question by using the formula we get,

$\implies \sf {(side)}^{2} =\: 81$

$\implies \sf side =\: \sqrt{81}$

$\implies \sf side =\: 9$

$\implies \sf\bold{\red{side =\: 9\: mm}}$

$\therefore$ The length of the side is 9 mm .
