### Exercise-12

**Solution 1:**

- Perimeter of a rectangle = 2 × length + 2 × breadth

Perimeter of a rectangle = 2 × l + 2 × b - ∴ Perimeter of a rectangle = 2l + 2b

Perimeter of a square = 4 × length of side

Perimeter of a square = 4 × a

∴ Perimeter of a square = 4a - Perimeter of a triangle = Sum of the lengths of the three sides of the triangle = a + b + c

∴ Perimeter of a triangle = a + b + c - Profit = Selling price – Cost price = s – c

∴ p = s – c

**Solution 2:**

- a × b = b × a
- n × 1 = n
