# 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

**Solution:**

Breadth of the rectangle = 30 cm

Perimeter of a rectangle = 130 cm

Perimeter of rectangle = 2 × [Length(l) + Breadth(b)]

130 cm = 2 × (l + 30 cm)

130 cm = 2l + 60 cm

2l = 130 cm - 60 cm

2l = 70 cm

l = 70/2 cm

l = 35 cm

Area of Rectangle = Length × Breadth

= (35 × 30) cm^{2 }

= 1050 cm^{2}
