Answer 2

Before, finding the answer. Lets find out on how we can find the answer.

• First, we must find the perimeter of the window by using the formula of :

$\boxed{ \sf Perimeter \: of \: Window =(2 \times l) + (2 \times b)}$

• As the Length and breadth is given in m and cm, we can convert it to cm.
• Now, we must multiply the number of windows and perimeter to get the total length.
• At last, we must multiply the rate with total perimeter.

Given :

• Length = 1m 30cm
• Breadth = 1m 20cm
• Windows = 6
• Rate = Rs. 5

To find :

• how much ribbon is required
• total rate

Solution :

• Conversation of m to cm.

1m 30 cm = 100 + 30

= 130 cm

1m 20 cm = 100 + 20

= 120 cm

Perimeter of Window = (2 × l) + (2 × b)

= 2 × 130 + 2 × 120 cm

= 260 + 240 cm

= 500 cm

Hence, 500 cm of ribbon is needed.

-------

6 windows = 500 × 6

= 3000 cm

Hence, 3000 cm of ribbon is needed for 6 windows.

--------

Rate for Ribbon :

As they have asked the rate in meter we have to convert it from cm to meter.

• 1 m = 100 cm

= 3000 ÷ 100

= 30 m

Rate for Ribbon = perimeter × rate

= 30 × 5

= ₹ 150

Hence, the Rate for Ribbon is ₹ 150.
