Answer:
61
Step-by-step explanation:
let the number be x then twice the number is 2x, hence
42 + 2x = 164 ( subtract 42 from both sides of the equation )
2x = 122 ( divide both sides by 2 )
x = 61
Hence the number is 61
Since we know [width = n] and [length = n + 4] multiply them together to get your answer:
n(n+4)
