# The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth. Also find the area

**Solution:**

The perimeter of a rectangular sheet = 100 cm

Length of the rectangular sheet (l) = 35 cm

Let the breadth be 'b' cm

Perimeter of a rectangular sheet = 2 (Length + Breadth)

100 = 2l + 2b

100 = 2 × 35 + 2b

100 = 70 + 2b

2b =100 - 70

b = 30/2

b = 15 cm

Area of a rectangular sheet = Length × Breadth

= 35 cm × 15 cm

= 525 cm^{2}
