The perimeter of a rectangle is 130 cm. If the breadth of the rectangle is 30 cm, find its length. Also, find the area of the rectangle.

Length = l
Breadth (b) = 30 cm
Perimeter = 130 cm
2(l+b) = 130
2(l+30) = 130
l+30 = 130/2
l = 65-30
Length = 35 cm
Area = Length × Breadth
Area = 35×30
Area = 1050 cm²
