Question

please write solution​

Answer 1

Step-by-step explanation:

length = 6x

breadth = x

length = 120cm

breadth = 120/6

= 30cm

perimeter = 2(a+b)

= 2(150)

= 300cm

Answer 2

Answer:

length 120

length =6*breadth

according to question

6*breadth=120

breadth =120/6

b=20

perimeter =2(l+b)

2(120+20)

2*140

280 cm
