The length of a rectangular flower bed is 2ft longer than the width. if the area is 6ft, then what are the exact length and width?

Step-by-step explanation:

we know that

The area of a rectangle is equal to

In this problem we have

so

------> equation A

-----> equation B

substitute equation B in equation A

The formula to solve a quadratic equation of the form is equal to

in this problem we have

so

substitute in the formula

 ------> the value positive is the solution

therefore

Find the value of L

------>

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
