Answer:
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
