Question

how many square metres of glass will be required for a window which has 12 panes each pane measuring 25cm by 16 cm . answer with solution​

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 2

HERE IS YOUR ANSWER :-

Dimension of each window pane = 25 by 16 cm.

Area if each panes = 25 × 16.

Area of each pane = 400cm^2.

Now,

The window has 12 panes, so the total area of 12 such panes =12 × 400.

Area of 12 panes = 4800 cm ^2.

Hence the area of glass would

required is = 0. 48 m^2.
