Answer 1

Answer:

Step-by-step explanation:

We Have :-

Door frame of dimension 6 m * 2 m

Wall dimension 10 m * 10 m

To Find :-

Cost of Painting the Wall

Formula Used :-

Area of rectangle = Length * Breadth

Solution :-

Wall

Area of wall = 10 * 10

                    = 100 m²

Door

Area of door = 6 * 2

                     = 12 m²

Area of Wall left

100 - 12

88 m²

Cost of Painting

1  m² = Rs 2.50

88 m² = Rs 2.50 * 88

          = Rs 220
