Answer 2

The number of tiles of dimensions 50cm ×50cm which will be required to cover the verandah is 1344 and the area of the verandah is $336m^2$

Step-by-step explanation:

Length of hall = 30 m

Breadth of hall = 20 m

Width of verandah = 3m

Outer length = 30+3+3=36 m

Outer breadth = 20+3+3=26 m

Area of verandah = $36 \times 26-(30 \times 20)=336m^2$

length of tile = 50 cm =0.5 m

Area of square tile = $0.5^2 = 0.25 m$

The number of tiles of dimensions 50cm ×50cm which will be required to cover the verandah =$\frac{336}{0.25}=1344$

Hence the number of tiles of dimensions 50cm ×50cm which will be required to cover the verandah is 1344 and the area of the verandah is $336m^2$
