A rectangle has a perimeter of 58 inches. The length is one more than three times the width

13.) define variables

14.) write a system of equations that show the two distinct relationships between the length and width

15.) explain why you could not solve this problem/narrow down the actual length and width of this rectangle unless you knew the second relationship - that fact that the length was one more than three times the width

13.)

l=length

w=width

p=perimeter

14.)

p=2l+2w

l=1+3w

15.)

58 in = 2 (1+3w) + 2w

58 = 2+8w

8w = 56

w=7 in

l=1+3 (7)

l=22in
