# Steps

Let x be the breadth.

Length = x+16

Area = (x+16)×x = x^2 +16x = 336

x^2+16x-336=0

(x+28)(x-12)=0

x=-28 or x=12

Length or breadth can not be negative

Hence x=12 breadth

x+16=12+16=28 =length

# Answer

Length =28

breadth =12

Let x be the breadth.

Length = x+16

Area = (x+16)×x = x^2 +16x = 336

x^2+16x-336=0

(x+28)(x-12)=0

x=-28 or x=12

Length or breadth can not be negative

Hence x=12 breadth

x+16=12+16=28 =length

Length =28

breadth =12
