Translate into a mathematical equation, solve and answer the question.
THE LENGTH OF A RECTANGLE IS THREE TIMES IT'S WIDTH. IF THE AREA OF THAT RECTANGLE IS 75 SQUARE FEET, WHAT IS THE LENGTH? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! L=3W
LW=75
3W*W=75
3W^2=75
W^2=75/3
W^2=25
W=SQRT25
W=5 ANS. FOR THE WIDTH.
L=3*5=15 ANS. FOR THE LENGTH.
pROOF:
5*15=75
75=75
