Answer 1

breadth=30

Step-by-step explanation:

perimeter=sum of all sides

42=12+x

x=30

Answer 2

Answer:

Breadth = 9 m

Step-by-step explanation:

Given :-

Perimeter = 42 m

Length = 12 m

To Find :-

Breadth

Solution :-

We know that

Perimeter = 2(l + b)

42 = 2(12 + b)

42/2 = 12 + b

21 = 12 + b

21 - 12 = b

9 = b

Hence,

Breadth is 9 m
