Question

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 1

the awnser is A

Explanation:

Answer 2

A:
`x^2+2x+1`

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=
`x+1`

We know that area of square =
`side * side`

Therefore, area of metal sheet used in square shaped traffic sign=
`(x+1)(x+1)=x^2+2x+1`

Hence, option A is true.

Answer : A:
`x^2+2x+1`
