Question

The length and breadth of a rectangle is 25cm amd 15 cm .Find ratio of <br />(a)its length to its breadth<br />(b)its length to its perimeter<br />(c)its breadth to its perimeter

Answer 1

heya!!

The length and breadth of a rectangle is 25cm amd 15 cm . Find ratio of -

Length = 25 cm
Breadth = 15 cm
Perimeter
= 2 ( l + b )
= 2 ( 25 + 15 )
= 2 ( 40 )
= 80 cm

(a)its length to its breadth - 25 : 15 = 5:3
(b)its length to its perimeter - 25 : 80 = 5:16
(c)its breadth to its perimeter - 15 : 80 = 3:16

hope it helps!!

Answer 2

$\:\:\:\: \Large \underline {\sf{Given\::}}$

➟ The length and breadth of a rectangle is 25 cm and 15 cm respectively

$\:\:\:\: \Large \underline {\sf{To\:Find\::}}$

➟ Ratio of

• its length to its breadth
• its length to its perimeter
• its breadth to its perimeter

$\:\:\:\: \Large \underline {\sf{Solution\::}}$

➟ Let us find the perimeter of rectangle

$\:\:\:\: \large \underline{\boxed{\sf{\pink{Formula\:used\::}}}}$ $\sf 2(l\:+\:b)$

➟ 2( 25 + 15 )

➟ 2 ( 40 )

➟ 80 cm

$\:\:\:\: \bigstar \: \large \underline {\sf{Perimeter\:=\:80\:cm}}$

• Let us find the Ratio :

(a) its length to its breadth

= 25 : 15 = 5 : 3

$\:\:\:\: \rightarrow \large \underline {\sf{Ratio\:=\:5:3}}$

(b) its length to its perimeter

= 25 : 80 = 5 : 16

$\:\:\:\: \rightarrow \large \underline {\sf{Ratio\:=\:5:16}}$

(c) its breadth to its perimeter

= 15 : 80 = 3 : 16

$\:\:\:\: \rightarrow \large \underline {\sf{Ratio\:=\:3:16}}$

Final ans is :

(a) 5:3

(b) 5:16

(c) 3:16

And we are done !
