Answer:
A:[tex]x^2+2x+1[/tex]
Step-by-step explanation:
We are given that a metal sheet which is required to make square -shaped traffic sign.
We are given that a square shaped traffic sign is shown with length of on side labeled as x+1.
We have to find an expression which is equivalent to area of metal sheet used in square shaped traffic sign
Length of square shaped traffic sign=[tex]x+1[/tex]
We know that area of square =[tex] side \times side[/tex]
Therefore, area of metal sheet used in square shaped traffic sign=[tex](x+1)(x+1)=x^2+2x+1[/tex]
Hence, option A is true.
Answer : A:[tex]x^2+2x+1[/tex]
