Question

Which expression is equivalent to the area of metal sheet required to make this square-shaped traffic sign?

Answer 1

Answer:

Hence, the expression for the area of the metal sheet used is:

$(x+1)^2=x^2+2x+1$

Step-by-step explanation:

It is given that a traffic signal is in the shape of a square such that its's one side is labeled as:

x+1.

We are asked to find the expression that is equivalent to the area of metal sheet required to make this square-shaped traffic sign.

The area of metal sheet used will be equal to the area of the traffic signal which is equal to the area of the square with side length (x+1).

Hence, the area of square(A) is:

$A=(x+1)^2\\\\A=x^2+1+2x$

Hence, the expression equivalent to the area of metal sheet used is:

$(x+1)^2=x^2+2x+1$

Answer 2

(x+1)^2
(x+1)(x+1)
x^2+x+x+1
The expression is x^2+2x+1
