This is the step by step explanation of your problem

Answer 2

The area of verandah is 336 m² and the number of tiles required to cover the verandah is 1344.

Explanation:

As per given , we have

A hall is of length 30 m and breadth 20 m.

It is surrounded by a 3 m wide verandah on the outside.

Then,  Length of verandah  = 30+3+3=36 m

Breadth of verandah= 20+3+3=26 m

Area of verandah = (Length of verandah x Breadth of verandah) - (Area of hall)

= (36 x 26) - (30 x 20 ) = 336 m²

Also, the side-length of tile = 50 cm =0.5 m   [ since 1 m = 100 cm]

Area of square tile = (side)² =(0.5)² =0.25 m²

The number of tiles of dimensions required to cover the verandah will  be

(Area of verandah ) ÷ (Area of square tile)

=( 336) ÷ (0.25) =1344

Therefore , the area of verandah is 336 m² and the number of tiles required to cover the verandah is 1344.
