1.	21. The length and breadth of rectangular field are 80, m and 60m,respectively.Twomutperpendicular passage. One is parallel to its length and having width 5 m while other is parallelbreadth having width 3 m are left in the central part. What is the total cost of passage at the rate dper square metre. What is the area of rest part of the field?costof passage attheper square metre What s the area of restpa
Answer» Area of road parralel to length =80×3=240 Now,Area of road parallel to breadth=60×3=180 Total area will be=240+ 180-33( because they are intersecting and 33 is coming two times )=240+180-9=411 hit like if you find it useful

Answer»

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
