A rectangular balcony has an area of 27 square feet and a perimeter of 24 feet. What are the dimensions of the balcony?

Answer 1

The given information is enough to write two equations in two unknowns:

(1) Perimeter = 2L + 2W = 24 ft

and

(2) Area = LW = 27 sq ft

These can be solved (for example, by substitution) to get W=3ft, L=9ft.
