Question

the length and hight of the room is 8m and 4m respectively the cost of painting of the four wall at the rateof5p per sq decimeter is 560 what is the breadth of the room​

Answer 1

Answer:

Area of one wall =length×height=5×8=40 sq.m

Area of another adjacent wall =width×height=3×8=24 sq.m

Area of 4 walls =2×40+24×2−4.5−2.25=128−6.75=121.25

Cost of painting the four walls =121.25×25=3,031.25 Rs.

So, we don't require statement III.
