Question

Geeta wants to put a wooden border around a photograph.if the length of the photograph is 35cm and its breadth is20cm, what will be the cost of putting the border at ₹65 per m?​​

Answer 1

Given : Length and Width of the photograph is 35 cm and 20 cm . Rate of framing is Rs.65 per m² .

To Find : Find the Cost of Framing

$\\ \qquad{\rule{200pt}{2pt}}$

SolutioN :

$\dag$ Formula Used :

• ${\underline{\boxed{\sf{ Perimeter {\small_{(Rectangle)}} = 2 \bigg( Length + Breadth \bigg) }}}}$

$\dag$ Calculating the Perimeter :

$\begin{gathered} \qquad \; \longrightarrow \; \; \sf { Perimeter = 2 \bigg( Length + Breadth \bigg) } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longrightarrow \; \; \sf { Perimeter = 2 \bigg( 35 + 20 \bigg) } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longrightarrow \; \; \sf { Perimeter = 2 \times 55 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longrightarrow \; \; {\underline{\boxed{\pmb{\sf{ Perimeter = 110 \; cm }}}}} \; {\red{\pmb{\bigstar}}} \\ \\ \\ \end{gathered}$

$\dag$ Calculating the Cost :

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { Cost = Perimeter \times Rate } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { Cost = 110 \times 65 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { Cost = \dfrac{110}{100} \times 65 } \qquad \bigg\lgroup {\purple{\sf{ 1 \; m = 100 \; cm }}} \bigg\rgroup \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { Cost = \cancel\dfrac{110}{100} \times 65 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { Cost = 1.10 \times 65 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; {\underline{\boxed{\pmb{\sf{ Cost = Rs. \; 71.5 }}}}} \; {\blue{\pmb{\bigstar}}} \\ \\ \\ \end{gathered}$

$\therefore \;$ Cost of Framing the photograph is Rs.71.5 .

Answer 2

Step-by-step explanation:

Length of the border = perimeter of the photo

:.length of 2rder = =2(l+b)

:. =2(35 m multiplied by 20)

..=2(700)

Cost = 65 multiplied by 14

Since the cost is rs 65 per m

Therefore ngth = 14m

..=1400^ prime prime cm^ prime prime
