I enjoy helping anyone that willing to succeed.

a) Perimeter of rectangle: __P = 2 * (Length + width)__

"The length if 12 more than the width" which means__ Length = Width +12__

--> P = 2 * [(w +12) + w]

--> 88= 2 * ( 2w + 12)

--> 88= 4w + 24

--> 64= 4w

--> w= 16

__ Length = 16 +12 = 28 m__

__ Width = 16 m__

b) Lisa score five more goal than Nicole which means __Lisa's scores= Nicole's scores + 5__

Tania score three less than Nicole which means __Tania's scores= Nicole's scores - 3__

__ Total goals = Lisa + Nicole + Tania__

--> 29= (N+5) + N + ( N - 3)

--> 29= 3N + (5 - 3)

--> 29= 3N - 2

--> 27= 3N

--> N = 9

__ Lisa = N +5 = 9 +5= 14 scores__

__Tania = N - 3 = 9 -3= 6 scores__

__ Nicole = 9 scores__
