Determine the width of a 72 square feet rectangular garden if the width

Question

Determine the width of a 72 square feet rectangular garden if the width is 1 meters less than the length

Answer 1

1 meter = 39.37 inches = 39.37 / 12 feet = 3.28 feet

 

1 square meter = 10.76 square feet

 

72 square feet = 72 / 10.76 square meters = 6.689 sq meters

 

x(x-1) = x^2 - x = 6.689

OR:

 

x^2 - x -6.689 = 0
