Answer 1

$\blue\bigstar$Question Given :

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

• $\dashrightarrow$Perimeter of a rectangle is 50cm. If its breadth is 10cm, what is its length.

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

$\pink\bigstar$Required Solution :

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

◈ Value Given to us :

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

• $\dashrightarrow$Perimeter of rectangle = 50 cm

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

• $\dashrightarrow$Breath of rectangle = 10 cm

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

$\red\bigstar$Required Diagram :

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 15cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 10cm}\put(-0.5,-0.4){\bf }\put(-0.5,3.2){\bf }\put(5.3,-0.4){\bf }\put(5.3,3.2){\bf }\end{picture}$

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

◈ Formula used Here :

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

• $\dashrightarrow$Perimeter = 2 ( l + b)

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

◈ Putting Value in Formula :

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

• $\dashrightarrow$P = 2 ( l + b) cm

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

• $\dashrightarrow$50 = 2 ( l + 10 ) cm

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

• $\dashrightarrow$25 = l + 10 cm

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

• $\dashrightarrow$l = 15 cm

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

• Length of rectangle 15 cm

$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;$

$\huge \bf{Question}$

$\:$

» Perimeter of a rectangle is 50 cm. If its breadth is 10 cm, What is its breadth.

$\:$

$\huge\bf{Given}$

$\:$

• Perimeter of a rectangle is 50 cm

• Its breadth is 10 cm

$\:$

$\huge \bf{To \: \: Find}$

• Its length

$\:$

$\huge \bf{Solution}$

$\:$

~We know that

.» P = 2 ( l+b )

$\:$

~Where

» P = Perimeter

» l = Length

» b = Breadth

$\:$

Working out the length :-

$\:$

» P = 2 ( l+b )

» 50 = 2 ( l+10 )

» 50/2 = l + 10

» 25 = l + 10

» l = 25 - 10

» l = 15 cm

$\:$

Hence, The length of the rectangle is 15 cm

$\:$

★Verification★

$\:$

» P = 2 ( l+b )

» P = 2 ( 15+10 )

» P = 2 × 25

» P = 50 cm.
