Answer 1

Answer:

78300 RS for expenditure for all the doors and windows for home

Step-by-step explanation:

Let's consider that I am living in home having 3 doors and 6 windows.

The measurements of each object is as per given below,

Doors required 72 inches high, 80 inches wide curtains.

Door's are in rectangle shapes,  

So, Area of rectangle is A = (high  * wide) sq/feet

for door 1 = 72 * 80

               ∴ 1296 sq/inches

so for 3 doors,

1296 * 3 = 3888 sq/inches

Now, Same for windows,

windows are 46 inches wide and 54 inches long.

So, as per rectangle formula for Area , We have

windows area of curtain A = 46 * 54 = 2484 sq/inches

and now, We have total 6 windows,

so, 2484 * 6 = 14904 sq/inches for windows.

So, we need total 3888+ 14904 = 18792 sq/inches

Now, We will have to convert inches into feet by using below formula ,

∴ 18792/12 = 1566 feet       ∵ 1 feet = 12 inches

So we need total 1566 sq/feet curtains.

as per rate of 50RS per square we need 1566 * 50 = 78300 RS for expenditure for all the doors and windows for home.
