2 मी रुंद व 1 मी उंच अशा पाच खिडक्यांना 125 रु चौमी दराने काचा बसविण्यासाठी किती खर्च येईल?
To find:
The total cost
Solution:
The dimensions of each window:
Width, w = 2 m
Height, h = 1 m
∴ The area of each window = width × height = 2 × 1 = 2 m²
∴ The area of 5 windows = 5 × 2 m² = 10 m²
Now,
If the cost for 1 m² of the window = Rs. 125
Then,
The cost for 10 m² of windows will be,
= Rs. 125 × 10 m²
= Rs. 1250
Thus, it will cost Rs. 1250 for five windows.
