Question

Lauren is sewing a quilt using fabric squares.
The length of a side of a fabric square is represented by the expression x + 4.
Which expression represents the area of a fabric square?

4x + 6
2x + 8
x + 4
x2 + 8x + 16

Answer 1

Answer:

Formula to find square area :- side × side

Here, sides = x+ 4

So,

= x( x + 4) 4 ( x + 4)

= x2 + 4x + 4x + 16

= x2 + 8x + 16

Hence, Option D
