Answer 2

Given:

• A square sheet whose perimeter is 32 cm is painted at the rate of Rs.5 per m².

To Find:

• Cost of painting of square sheet

Solution:

Perimeter of Square sheet = 32 cm

→ Perimeter of square = 4 × side

→ 32 cm = 4 × side

→ Side = 32/4

→ Side = 8cm

Side of square = 8/100 = 0.08m

Now,

→ Area of Square = Side × Side

→ Area of Square = 0.08 × 0.08

→ Area of Square = 0.0064 m²

Now,

→ Cost of painting the square sheet = Area of square × Rate of painting the square sheet

→ Cost of painting = 0.0064 × 5

→ Cost of painting = ₹ 0.032

Therefore :

• Cost of painting the square sheet is Rs. 0.032
