Please can someone help; this is not cheating btw.

By determining the area of the square, we get x^{2} +4x = 3.

Step-by-step explanation:

Step 1:

The area of a square is given by squaring its side length.

The given squares side length is (x+2) cm.

The area of a square = a^{2} . Here a is the side length.

The area of the square is given as 7 cm².

Step 2:

Substituting the value of a in the equation, we get

7 = (x+2)^{2} = x^{2}  + 4x + 4.

Taking the x values on one side and the constants on the other side, we get

x^{2} +4x= 7-4 =3.

So x^{2} +4x = 3.

So it has been proved.

sp2606 [1]
Width = Length - 2
Area = L x W
y = x * ( x - 2 ) 
If the point is ( 2, 0 ): x = 2, y = 0 
y = 2 * ( 2 - 2 ) = 2 * 0 = 0 ( area )
Answer:
B ) The area is 0 if the length is 2.
