Alicia wants to fence a triangular area in her yard with 1 leg (L) along 1 side of a shed. The second leg of the triangle is half the length of the shed. The third leg will be 3 feet shorter than twice the length of the second leg. The perimeter of the triangle is 32 feet. Which equation could Alicia use to determine the length of the first leg of the triangle?

L+2L+L−3=32, cap l plus 2 liters plus cap l minus 3 is equal to 32

L+L2+L=32+3
, , cap l plus cap l over 2 plus cap l is equal to 32 plus 3,

L+(L2)+L−3=32
, cap l plus open paren cap l over 2 close paren plus cap l minus 3 is equal to 32

L+L2+2L=32−3
