If the length and breadth of a room are increased by 2 metres, the area is increased by 40 square metres. If length is
increased by 2 metres and breadth is decreased by 2 metres, the area is decreased by 12 square metres. Find the
length and breadth and the perimeter of the room.
​

Answer 1

length is 8 breadth is 10

perimeter is 36sq.m

Answer 2

Answer:

Perimeter of the room = 30 cm

Area = 44sqm

Step-by-step explanation:

I took length as 9 increased by 2 = 9 + 2 = 11

I took Breadth as 2 increased by 2 = 2 + 2 = 4

Area as 29sqm + 40 = 69sqm

Formula to find perimeter of Rectangle = 2 x (l + b)

= 2 x (11 + 4) = 2 x 15 = 30cm

Formula to find Area of Rectangle: l x b

= 11 x 4 = 44sqm
