Question

The length,breadth and height of a room are 5m,4m,and 3m, respectively. find the cost of white washing the inner of the room and ceiling at the rate of rupees50 square metre​

Answer 1

Answer: rs 3700

Step-by-step explanation:

given that,

length = 5 m  

breadth = 4 m  

height = 3 m  

area of wall = 2h (L+  b)

                    = 2 * 3 (4 +5 )

                    = 6*9

                    = 54 sq m

area of cieling = l*b

                        = 5 * 4  

                       = 20 sq m

total area= area of cieling + area of cieling  

              = 54 + 20 sq m

              = 74 sq m

cost of white washinf for 1 sq m = rs 50

            so for 74 sq m = 50 * 74 sq m

                                       = rs 3700
