Answer 1

Answer

Given:-

There are 12 panes and each measures 25cm × 16cm.

To find:-

The area of the glass required.

Formula used:-

$\pink{\fbox{Area = Length × Breadth}}$

Solution:-

⟹ Area of one window pane = $400 \: cm^{2} \: (25 \times 16)$

⟹ Area of glass required = $400 \times 12$

∴ Sq. metre of glass required = $\frac{4800}{100}$

∴ 48m² of glass is required
