2

Step-by-step explanation:

Perimeter of rectangle=130cm

⇒2(length+breadth)=130cm

⇒2(length+30)=130

⇒ length+30=

2

130

⇒ length+30=65

⇒ length=65−30=35cm

Now area of rectangle=length×breadth=35×30=1050cm

Answer 2

Answer:

35 cm (a)

Step-by-step explanation:

p = 2(l+b)

130 = 2 (l + 30)

130 = 2l + 60

2l = 130- 60

l = 70/2

l = 35
