Answer:

₹996

Step-by-step explanation:

Area painted = area of wall - area of wall posture

Area of a rectangle = length x breadth

= 10.5m x 8.5m = 89.25m^2

Area of a square

length x length

2.5m x 2.5m = 6.25m^2

Area painted =  89.25m^2 -  6.25m^2 = 83m^2

Total cost of area painted = 83m^2 x 12 = 996

×imagine this is a flattened pyramid box. When you fold along the dotted lines you can see which sides are equivalent.

Add up the areas of each piece.

Two identical rectangular pieces 7 × 10
2(7)(10) = 140

One small rectangular piece 6 × 7
7(6) = 42

Two identical triangles
2(0.5)(6)(8) = 48

Add up all the pieces
140 + 42 + 48 = 230
