PART A:  The garden below is 4 feet long and 10 feet wide.  The length and width of the original garden are going to be enlarged by x feet.  Circle all of the expressions below that will be equivalent to the perimeter of the new garden.  

old garden

4 ft

10 ft

a.	P = (4 + x) + (10 + x) + (4 + x) + (10 + x) 

b.	P = (4 + x)(10 + x) 

c.	P = 4(x + 7)

d.	P = 4x + 10x

new garden

4 + x

10 + x

e.	P = 4x + 28

f.	P = 4(x+4)(x+10)

g.	P = 2(x + 7)

		

PART B:  The garden below is 8 feet long and 12 feet wide.  The length and width of the original garden are going to be decreased by x feet.  Circle all of the expressions below that will be equivalent to the perimeter of the new garden. 

old garden

8 ft

a.	P = 4(8 – x)(12 – x) 

b.	P = 20 + 2x 

12 ft

c.	P = 2(8 – x) + 2(12 – x)

d.	P = -4x + 40

e.	P = 4(10-x)

8 - x

new garden

f.	P = (8 – x) + (12 – x)

g.	P = 40 – 4x
12 - x
