Question

Find the perimeter of the rectangle of length 17 cm and breadth 13 cm

Answer 1

Answer:

length = 17 cm , breadth = 13 cm

perimeter = 2(l+b)

= 2(17+13)

= 2× 30

= 60 cm

Answer 2

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 17 cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 13 cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$

$\LARGE\mathfrak{\pink{Solution:-}}$

$\large\mathbb{\orange{GIVEN:-}}$

Length of the rectangle = 17 cm

Breadth of the rectangle = 13 cm

$\large\mathbb{\purple{TO \:FIND:-}}$

Perimeter of the rectangle.

$\large\mathbb{\green{FORMULA:-}}$

Perimeter of a rectangle = 2 (Length + Breadth)

$\large\mathbb{\red{ACCORDING \:TO\: THE\: QUESTION:-}}$

$Perimeter = 2 (Length + Breadth) \\ \\ \implies \: 2(17 + 13)\\ \\ \implies \:2 \times 30 \: \\ \\ \implies \: 60 \: {cm}^{2}$

$\large\mathbb{\purple{ANSWER:-}}$

$\\ \implies \boxed{ 60 \: {cm}^{2} }$

$\large\mathbb{\pink{FOCUS\: ZONE:-}}$

• Both Length and Breadth will be in same unit , i . e. , in cm .

$\large\mathbb{\red{EXTRA \: INFORMATION:-}}$

$Area = Length× Breadth$

$Diagonal= \sqrt{{( Length )}^{2} + {{( Breadth )}^{2} } }$
