Let the length and breadth of the rectangle be x and y.
Area of rectangle is A = xy
Therefore, the new length will be = x-5
Therefore, the new breadth will be = y + 3
So new area will be xy-9
Now the new relation will be (x+3)(y+2)=xy+67
.
Cross – multiplication method–



Therefore, the length is 17 and breadth is 9.
40% is close to 50% which is = to 1/2
So just divide 60 by 2. which would be around 30
this is the best way i could explain, I hope this helps
