Question

the area of rectangle is 120msquare if it's breadth is 12m find the perimeter of rectangle
​

Answer 1

$\huge \sf \red{Answer}$

$\large \sf{Given:-}$

$\sf \blue{Area = 12 {0m}^{2} }$

$\sf \blue{Breadth = 12m}$

$\sf \red{Area \: of \: rectangle = l \times b}$

$\sf {= > 120 = l \times12 }$

$\sf{ \frac{120}{12} = l }$

$\sf{length = 10m}$

$\sf \red{Perimeter = 2 \times (l + b)}$

$= > 2 \times (10 + 12)$

$= > 2 \times 22 = 44$

$\sf \blue{So \: perimeter \: of \: given \: rectangle \: is \: 44m}$

$\sf \red{❥Hope \: it \: helps \: you....}$

Answer 2

Given

Length of rectangle ⇒ 12 m

Area of rectangle ⇒ 60 m²

_______________________________

To Find

Breadth of rectangle

Perimeter of Rectangle

_______________________________

Solution

Area of Rectangle ⇒ Length × Breadth

Length ⇒ 12 m

Breadth ⇒ x m

Breadth ⇒ Area ÷ Length

Breadth ⇒ 60 ÷ 12

Breadth ⇒ 5

∴ Breadth = 5 m

Perimeter of Rectangle ⇒ 2 (Length + Breadth)

Length ⇒ 12 m

Breadth ⇒ 5 m

Perimeter of Rectangle ⇒ 2 (12 + 5)

Perimeter of Rectangle ⇒ 2 (17)

Perimeter of Rectangle ⇒ 34

∴ Perimeter of Rectangle = 34 m
