Question

15)
The perimeter of a rectangle is 122 cm If its breadth is 2.- cm,find ts length
e Simplify and write in exponential form
(21​

Answer 1

Answer:

2(l+b)=122

2(l+2)=122

2l+4=122

2l=118

l=59

Answer 2

Answer:

Perimeter of rectangle=p=122cm.

Breadth=b=2cm.

Length=l=?.

Perimeter of rectangle==p=2(l+b).

122=2(l+2).

122=2l+4.

2l=122-4.

2l=118.

l=118/2.

l=59.
