Find the perimeter and area of each tile pattern.

Perimeter is all the outside dimensions added together.

Area is length x width of each shape added together.

1.  Perimeter = x + x + 1 + 1 + x + 1 +x +1 + (x-1)+1 + x

Simplify by combining like terms:

5x + (x-1) + 5 = 4x +4

Area = x^2 + 1x + 1^2 + 1x

Simplify:

x^2 + 2x +1

2. Perimeter: x +1 + x+1+x+1+x+1+x+1+x+1

Simplify:  6x +6

Area: 1x + 1^2 + 1x +1^2 +1x

Simplify: 3x + 2

3. Perimeter: y+y+1+1+1+1+y-1+1+y

Simplify: 4y + 4

Area: y^2 + y +1

4. Perimeter: 1+x+x+x-1+1+1+1+x+x+1+1

Simplify: 5x + 7

Area: 1^2 + 1^2 + 1x +x^2

Simplify: x^2 + x + 2
