Question

what would be the cost of painting a wall 27 feet long and 15 feet wide if the painter charges rupees 20 to paint per square feet​

Answer 1

Answer:

Rs.8100

Step-by-step explanation:

length of the wall = 27 feet

breadth of the wall =15 feet

so

Area of the wall=length * breadth

Area of the wall =27*15

                          = 405 feet square

Cost of painting wall per square feet = Rs.20

So

cost of painting the wall = Area of the wall * cost of painting per square feet

                                         = 405*20

                                        = Rs.8100

Answer 2

Answer:

8100 rupees.

Step-by-step explanation:

Given :

Length of wall = 27 feet

Width of wall = 15 feet

Cost of 1 square feet = 20 rupees

Formula used :

Area of rectangle = length(l) ×breath(b)

Solution :

Area of the wall (rectangular) = l×b

Area of the wall =27×15 ft ²

Area of the wall =405 ft²

Now,

Cost of 1 ft² = 20 rupees

Cost of 405 ft² = 405×20 =8100 rupees

Therefore, the cost of painting the wall is 8100 rupees.
