Answer 2

Step-by-step explanation:

Hi Dear ! 

The Room Dimensions are : 

Length = 6 m 

Breadth = 5 m 

height = 4 m 

LSA of cuboid = 2h(l+b) 

= 2 x 4(6 + 5) = 8 x 11 = 88 m²

Dimensions of one of the door 

height  = 2 m 

length = 1.5 m 

Area of two doors = 2 x 2 x 1.5 = 6 m²

Dimensions of one of the window 

height = 1 m 

length = 1 m 

Area of four windows = 4 x 1 x 1 = 4 m²

Area to be distempered = 88 - 6 - 4 = 78 m²

Cost of distemper = 25 x 78 = ₹ 1950
