Question

a room 12.5m long and 10.5m wide is surrounded by a verandah 2m wide all around it. find the area occupied by the verandah.

Answer 1

Original Length = 12.5 m
Original Breadth = 10.5 m
Area = Length× Breadth= 131.25 m²

After adding the width of Verandah :

New Length = 12.5+2+2= 16.5 m
New Breadth = 10.5+2+2 = 14.5 m

New Area = Length × Breadth = 239.25

Now ,

Area of Verandah = New Area - Original Area = 239.25-131.25 = 108 m² .

Answer 2

Heya!!

Length of room = 12.5 m,
Breadth of room = 10.5 m

Area of a room = 12.5 * 10.5 m^2

= 131.25 m^2

Since it is surrounded by a verandah 2m wide all around,

Whole length = 12.5 + 2 + 2 m

= 16.5 m.,

Whole Breadth = 10.5 + 2 + 2 m

= 14.5 m.

Area = 16.5 * 14.5 m^2

= 239.25 m^2

Hence area occupied by verandah = 239.25 m^2

Area btw them = 239.25 - 131.25 = 108 m^2

Hope it helps uh!!
