Question

door frame of dimensions 6 metre X 3.5 metre is fixed on the wall of dimension 12 x 11 find the total labour charges for painting the wall if the labour charges for painting 1m sq of the wall at rupees
4.50 ​

Answer 1

Answer:

509.5

Step-by-step explanation:

area which we can paint is area of fixed wall- area of door frame

area of fixed wall is 12*11=132

area of door frame is 6*3.5=21.0

area of wall which we can paint = 132-21

= 111.

charges for paiting 1 metre square is 4.5

then for 2 it will be 4.5*2 =9

then for 111 it will be 4.5*111= 509.5
