SOMETHING BESIDES THE SHAPE IS CHANGING EVERY TIME HACKER SWITCHES THE FIELD.

AND IF WE DON'T FIGURE IT OUT FAST, RADOPOLIS WILL BELONG TO HACKER.

<Inez> AND SO WILL I. I GOT A PLAN.

SQWACK IT!

<Inez> HERE, TAKE THE SQWACK PACK.

<Jackie> OKAY, HERE'S THE FIELD I SKATED ON.

4 FENCE PIECES THIS SIDE AND THIS SIDE.

<Inez> AND 9 FENCE PIECES HERE AND HERE.

FOR A GRAND TOTAL OF 26 FENCE PIECES AROUND.

THE LEGAL PERIMETER.

NOW LET'S CHECK MATT'S FIELD.

YOU KNOW, IT LOOKS LIKE MAYBE YOU DID HAVE LESS ROOM INSIDE THAN JACKIE.

HOW COULD THERE BE LESS ROOM INSIDE?

ROOM INSIDE... THAT'S IT!

WHAT'S INSIDE IS THE AREA.

WE NEED TO CHECK THE AREAS.

AND AREAS MEANS SQUARES.

TRY ADDING SQUARES TO THE PICTURES.

OH MAN, LOOK AT THAT!

1, 2, 3, 4 TIMES 9.

MY FIELD HAS 36 SQUARES INSIDE.

<Matt> 28, 29, 30.

HEY!

MY FIELD HAS 30 SQUARES INSIDE.

NO WONDER I RAN OUT OF ROOM!

THIS IS UNBELIEVABLE!

CHANGE THE SHAPE AND THE ROOM INSIDE CHANGES TOO.

EVEN THOUGH THE DISTANCE AROUND THE OUTSIDE STAYS THE SAME.

IT'S PRETTY AMAZING, BUT THE PICTURES DON'T LIE.

DIFFERENT SHAPES WITH THE SAME PERIMETER CAN HAVE DIFFERENT AREAS INSIDE.

COME ON, WE HAVE TO FIGURE OUT HOW MUCH ROOM I HAVE TO SKATE ON.

<Jackie> YOURS IS 2 BY 11.

STILL 26 FOR THE PERIMETER.

WHAT'S THE NEW AREA INSIDE?

22 SQUARES.

THAT'S 8 LESS THAN MATT HAD AND 14 LESS THAN YOU HAD TO BIKE ON, JACKIE.

I'M AFRAID HACKER'S CHANGES DON'T GIVE YOU MUCH AREA TO COMPETE IN, INEZ.

NO WAY INEZ CAN WIN WITH SO LITTLE ROOM INSIDE.

SHE'S BOUND TO GO OUT!

BOUND TO GET A LOW SCORE!

BOUND TO BE CHEERING ON HACKER FOR THE REST OF HER LIFE!

COACH, WHAT DO I DO?
