Question

jack1 · Answer

$$P = 2L + 2W$$
$$P = 2(100) + 2W$$
$$P = 200 + 2W$$ ... whats a yard...?
like how many feets is it ...?
and when will you convert to metric system instead of quartz, fathoms, farenheit and ounces   ;D

i was just teasin, sorry     ;P
so 3 ft in a yrd
so P = 920 ft = 920/3 yrds = 306.66 yrds
306.66 = 200 + 2W
so W = ...??  @fluteprincess ?

jack1 · Answer

rectangle made up of Length ( L ) and Width ( W )
and we were just told that our rectangle is 100 yrds Long
so length = 100 yards = 300 feet ... yeah?|dw:1380898664220:dw|

next part:
The perimeter of the playing area is 920 feet. The formula for the perimeter of a rectangle is P = 2l + 2w.
first: convert everything into the one unit of measurement
so everything has to bee in feet OR
everything has to be in yards

so 920 ft / 3 = 306.66 yards
so perimeter = 306.66 yards
