The length of a rectangle is twice its breadth. if its length is decreased by 4 cm and breadth is increased by 1 cm, the area of the rectangle is increased by 198
sq. cm. what is the length of the rectangle?
a. 18cm
b. 16cm
c. 40cm
d. 20cm

Length will be 25 cm which is not given in bellow option

Step-by-step explanation:

Let breadth of the rectangle is b

According to question length l = 2b

So area

Now length is decreased by 4 cm

So length = 2b -4

And breadth increased by 1 cm

So breadth = b+1

So New area

As the area is increased by

So

Length can't be negative so none of the option is correct
