Answer 2

Answer: Rs. 151.25

Step-by-step explanation:

Area to Color =

TSA of Room - Area of door - {(No. of windows)*(Area of Each Window)}- Area of Floor

Now TSA = l*b*h = 7*6.5*4.5=204.75 sq. m

Area of Flooe l*b =45.5 sq. m

Area of Door = 3*1.4=4.2 sq. m

No. of Windows = 4

Area of each window = 2*1 = 2 sq. m

Area to Color = 204.75-{(4)*(2)}-45.5 =204.75-8-45.5=204.75-(8+45.5)=204.75-53.5=151.25 sq .m

Cost Per meter square = Rs. 1.

Cost for 151.25 sq. m = Rs 151.25*1= Rs. 151.25
