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
