  1. 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

    Thus, the area of rectangle is 1050cm

  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

    2

    Thus, the area of rectangle is 1050cm
