Answer:

Rs 7200

Step-by-step explanation:

area of a rectangle = breadth x length

Given:

  • breadth = 32 m
  • length = 75 m

⇒ area = 32 x 75 = 2400 m²

Given:

cost per m² = Rs 3

⇒ cost = 3 x 2400 = 7200

Answer:

Rs 7200

Find the area of wall:

area of rectangle: Length * Width

  • length * width
  • 75 * 32
  • 2400 m²

[tex]\sf cost \ of \ painting =\sf area \ of \ wall *area \ painting \ cover}[/tex]  as said   ** 1 m costs Rs 3 **

using the equation:

  • cost of painting = 2400 * 3
  • cost of painting = 7200

Therefore, the cost of painting is Rs 7200
