1. 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.

2. Given:–

   ● Perimeter of Rectangle = 130 cm

   ● Breadth of rectangular = 30 cm

   To Find:–

   ● Length of the rectangle

   ● Area of a rectangle

   Solution:–

   Perimeter of Rectangle = 2(l+b)

   => 130 = 2(l+30)

   => 130/2 = l + 30

   => 65 – 30 = l

   => l = 35 cm

   Area of rectangle = l × b

   = 35 × 30

   = 1050 cm²
