Answer:

hiii!!!

here's ur answer frnd...

given:-

length of the room=12.5m

breadth of the room=10.5m

area of the room=l×b

=12.5×10.5

=131.25m²

length of the verandah=12.5+2+2

=12.5+4

=16.5m

breadth of the verandah=10.5+2+2

=10.5+4

=14.5m

area=l×b

=16.5×14.5

=239.25m²

area of the verandah=239.25-131.25

=108m²

hope this helps u...

Answer 2

Given data : A room 12.5 m long and 10.5 m wide is surrounded by a verandah 2m wide all around it.

To find : The area occupied by the verandah.

Solution : Here, we know that,

• Width of the verandah : 2 m

• Length of the room : 12.5 m

• Breadth of the room : 10.5 m

Now,

➜ Area of the room = length * breadth

➜ Area of the room = 12.5 * 10.5

➜ Area of the room = 131.25 m²

Now, a/c to given data ;

• Length of the room with width of the verandah : 12.5 + 2 * (2) = 12.5 + 4 = 16.5 m

• Breadth of the room with width of the verandah : 10.5 + 2 * (2) = 10.5 + 4 = 14.5 m

Now,

➜ Area of the room with verandah = length * breadth

➜ Area of the room with verandah = 16.5 * 14.5

➜ Area of the room with verandah = 239.25 m²

Now,

➜ Area of the verandah = {Area of the room with verandah} - {Area of the room}

➜ Area of the verandah = 239.25 - 131.25

➜ Area of the verandah = 108 m²

Answer : Hence, area of the verandah is 108 m².
