Answer 1

Answer:

perimeter = (4b + 12)m or 4 ( b + 3 )m

Step-by-step explanation:

according to question

length = breadth + 6 m

let's,

breadth = b m

then ,

length = b + 6 m

perimeter of rectangle = 2( length + breadth)

= 2 ( b +6 + b )

= 2 ( b + b + 6 )

= 2 ( 2b + 6 )

= 2× 2b + 2 × 6

= 4b + 12 mor 4 ( b + 3 )m
