Answer 1

Answer:

hi mark me as Branilyest branilyest branilyest branilyest branilyest branilyest

Step-by-step explanation:

given, area= 25x²-35x+12.

to find, perimeter of a rectangle.

so, by factorising the area (25x²-35x+12) 25x²-35x+12. = 25x²-15x-20x+12.

now taking the commons, =5x(5x-3) -4(5x-3) =(5x-4) (5x-3)..given, area= 25x²-35x+12.

to find, perimeter of a rectangle.

so, by factorising the area (25x²-35x+12) 25x²-35x+12. = 25x²-15x-20x+12.

now taking the commons, =5x(5x-3) -4(5x-3) =(5x-4) (5x-3)..

breadth=5x-3. now, perimeter= 2(l+b) = 2 [ ( 5x-4) + (5x-3)] = 2 [5x-4+5x-3]
