Question

Length and breadth of a rectangular field are 80 m and 60 m respectively. Two mutually perpendicular passage. One is parallel to its length and having with 5m while other is parallel to its breadth having with 3M are left in the central part. what is the total cost of passage at the rate of 15 per square metre .what is the area of rest part of the field

Answer 1

Area of road parralel to length =80×3=240

Now,
Area of road parallel to breadth=60×3=180

Total area will be=240+ 180-3*3( because they are intersecting and 3*3 is coming two times )
=240+180-9
=411
