The length of an airport is 1 mile more than twice the width the area is 21 square miles identify the legth and width of the airport?
Let the length be (2x+1) and the width be x:
length*width = area
(2x+1)*x = 21 square miles
2x2+x-21 = 0
Solving the above quadratic equation works out as:
x = -7/2 or x = 3 it must be the latter because dimensions can't be negative.
Therefore: length = 7 miles and width = 3 miles

What is the perimeter of a square with an area of 800?
Area = Legth x Width In a square, Length = Width Therefore Area = Length x Length (or Width x Width) Area = Length squared Length = Square Root of 800 Perimeter = 4 x length Perimeter = 4 x Square Root of 800 Perimeter = 113.14
