3X + 5 = 2X
X + 5 =0
X = -5
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.
If your question was (c+1)²...
(c+1)(c+1)
c² + c + c + 1
c² + 2c + 1
