The perimeter of a rectangular field is 100 feet. which *could not* be the length and width of the perimeter?
a) l=20 w=30
b) l=10 w=40
c) l=49 w=1
d) l=50 w=50

D) L=50 W=50

Step-by-step explanation:

Just "plug and chug" these numbers and see which doesn't work.

A is not it, 20+30=50 (then *2 because we need 4 sides not just 2) 50*2=100

B isn't it, 10+40=50*2=100

C ain't it either 49+1=50*2=100

D is the answer 50+50=100*2=200
