Question

how many square metre of Glass will be required for a window which has 12 pane each measuring 25 CM by 16 cm​

Answer 1

Answer:

Step-by-step explanation:

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

$<b>$
so the area of the panel will be

$1cm × 25 cm$
$=400cm^2$

so the area of 12 panels would be

$12×400cm^2$
$4800cm^2$

on converting to m^2

$\frac{4800}{100×100}$

$0.48m^2$
