Find a formula for the described function. a rectangle has area 49 m2. express the perimeter of the rectangle as a function of the length l of one of its sides. p(l) = the domain of p. (assume the length of the rectangle is larger than its width. enter your answer using interval notation.)

Step-by-step explanation:

The area (A) of a rectangle is equal to the length (L) of one of its sides times its width (w)

(eq. 1)

And its perimeter can be calculated with the next formula:

P=2(L+w) (eq. 2)

Solving for w in eq. 1, and plugging it into eq. 2

(eq. 3)

(eq. 4)

We know that A=49m^2, plugging in this value into eq. 4, we finally get into the

If the length of the rectangle is larger than its width:

We know that a length can't be negative value, so the only valid interval is L>7. The domine of P is then:

L>7

stops on an even number.
