Question

Calculate the perimeter of a rectangle whose area is 25x2 – 35x + 12

Answer 1

hello user.

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)..

now,

length = 5x-4

breadth=5x-3

now,

perimeter= 2(l+b)

= 2 [ ( 5x-4) + (5x-3)]

= 2 [5x-4+5x-3]

= 2 (10x-7) ....... answer

please follow me if it helps you..
