Answer 2

Let the length of the rectangle = x units.

Let the breadth of the rectangle = y units.

Area of the rectangle = x * y.

Condition (1): 

Given that,

Length is reduced by 2 units = x - 2.

Breadth is increased by 2 units = y + 2.

Given that area gets reduced by 6 square units = xy - 6 

(x - 2)(y + 2) = xy - 6

 xy + 2x - 2y - 4 = xy - 6

2x - 2y = - 2 -------- (1)


Given,

Condition (2) : 

Length is increased by 3 units = x + 3.

Breadth is decreased by 2 units = y + 2

The area is increased by 79 square units.

(x + 3)(y + 2) = xy + 79

xy + 2x + 3y + 6 = xy + 79

2x + 3y = 73    ---------- (2)


On solving (1) & (2), we get

2x - 2y = -2

2x + 3y = 73

---------------------

-5y = -75

y = 15.  


Substitute y = 75 in (2), we get

2x + 3y = 73

2x + 3(15) = 73

2x + 45 = 73

2x = 73 - 45

2x = 28

x = 14.


Therefore the length of the rectangular plot = 14units.

Therefore the breadth of the rectangular plot = 15units.


Hope this helps!
