Answer 2

Answer:

A saree is 6 m long and 1.2 m wide. A border of width 30 cm is printed along its sides. Find the cost of printing the border at 1 Rs per 100 cm.

It is Rs 468

Step-by-step explanation:

First we need to find out the area of square.

We know that

Area=l×b

$= 6 \times 1.2 {m}^{2} \\ = 7.2 {m}^{2}$

Now we need to find out the area of saree with border.

Length=6.6 cm by adding 0.3 twice

Breadth =1.8 by adding 0.3 twice

Area=l×b

$= 6.6 \times 1.8 {m}^{2} \\ = 11.8 {m}^{2}$

Now we need to find area of border.

11.88-7.2=4.68 m^2

Convert it to cm

$4.68 {m}^{2} \\ \\ = 4 .68 \times 10000 \\ =46800 \: cm$

It is 10000 because 100×100

Now rate of painting =

$\frac{1}{100}$

Cost of painting =

$\frac{1}{ 1\cancel{00}} \times 468 \cancel{00} \\ \\ = rs \: 468$
