Answer:

$W=(x-6)\ m$

Explanation:

we know that

The area of rectangle is equal to

A=LW

we have

$A=(x^(2) -11x+30)\ m^2$

$L=(x-5)\ m$

substitute the given values in the formula of area

(x^(2) -11x+30)=(x-5)W

Remember that

x^(2) -11x+30=(x-5)(x-6) ----> by completing the square

substitute

(x-5)(x-6)=(x-5)W

Simplify

$W=(x-6)\ m$
