Question

how many square meter of glass will be required for a window which has 12 panes each measuring 25cm by 16cm?

Answer 1

Solution:-
Length of the window pane = 25 cm and breadth = 16 cm
Area of one window pane = 25*16 = 400 sq cm
Area of 12 such window panes = 400*12
Area of 12 window panes = 4800 sq cm
Since 1 sq m = 10000 sq cm
So, required glass for 12 window panes = 4800/10000 
= 0.48 sq m
Answer.

Answer 2

Answer:Length of the window pane = 25 cm and breadth = 16 cm

Area of one window pane = 25*16 = 400 sq cm

Area of 12 such window panes = 400*12

Area of 12 window panes = 4800 sq cm

Since 1 sq m = 10000 sq cm

So, required glass for 12 window panes = 4800/10000 

= 0.48 sq m
