Answer 2

Answer:

LENGTH = 20cm

BREADTH = 12cm

Step-by-step explanation:

PERIMETER FORMULA = 2( l + b) cm

LENGTH = x cm

BREADTH = (x - 8) cm

= 2( x + (x-8)) = 64

= 2 ( x + x -8) =64

= 2 ( 2x -8 ) =64

= 4x - 16 = 64

= 4x = 64 +16

= 4x = 80

= x = 80 / 4

= x = 20

LENGTH = 20 cm

BREADTH = (20 - 8) cm

= 12 cm

CHECKING -------=

= 2 ( 20 + 12 )

= 2 × 32

= 64 cm
