Question

When 3 is subtracted from length and breath of the rectangle, the perimeter becomes 24. What is the mathematical form of the statement ? ​

Answer 1

Answer:

Let the length of the rectangle be x and breadth be y

then A/Q perimeter will be (x-3)(x-y)

(x-3)(x-y)=24

xy-3x-3y+9=24

xy-3x-3y=15

-3(x+y)+xy=15

(x+y)+xy=-5
