please answers this question if you know the answer then only onlyanswer ch linear equation​

Answer 1

Step-by-step explanation:

Let the breadth of the rectangle be x cm

length of the rectangle is x+6 cm

Now the length and breadth are increased by 3 cm

So,. breadth is x+3 cm

length is x+3+6 i.e x+9 cm

area of rectangle = (x+9)( x) - 84cm²

(x+12) (x+3)= x²+9x + 84 cm²

x²+12+ 3x +36 = x² +9x+ 84cm²

15x -9x = 84-36

6x = 48

x= 8

breadth = 8cm

length = 8+ 9= 17cm
