Given length of square x + 4.
Area of square with side S is given by .
Therefore are of square with side x + 4 is given by
Area of square =
Thus, x2 + 8x + 16 expression represents the area of a fabric square.
Sides given by
- 10
- x+2
- x+5
- 2x+3
Opposite sides must be equal
Let's check once
Find sides now
- 10in
- 2+2=4in
- 2+5=7in
- 2(2)+3=4+3=7in
One pair of opposite sides are equal but others not .
