Answer:

heyo \: mate

Step-by-step explanation:

Perimeter of rectangle=130cm

⇒2(length+breadth)=130cm

⇒2(length+30)=130

⇒ length+30=2130

⇒ length+30=65

⇒ length=65−30=35cm

Now area of rectangle=length×breadth=35×30=1050cm2

Thus, the area of rectangle is 1050cm2.

Answer:

Step-by-step explanation:

Perimeter of a rectange = 2× (l + b)

                      ⇒        130 = 2× (l + 30)

                      ⇒      130/2 =l + 30

                      ⇒       65 =l + 30

                     ⇒      65-30=l

                     ⇒       35 = l

hence the length of the rectangle is 35 cm
