Which expression is equivalent to the area of metal sheet required to make this square-shaped traffic sign? A square shaped traffic sign is shown with length of one side labeled as x plus 1. x2 + 2x + 1 x2 + x + 1 x2 + 2x x2 + 1

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 signLength 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]
