Answer:
Step-by-step explanation:
Area of the rug is given by the trinomial,
r² - 2r - 35
Since, area of the rectangular rug = Length × Width
Now we will convert the given trinomial in the factored form,
r² - 2r - 35 = r² - 7r + 5r - 35
= r(r - 7) + 5(r - 7)
= (r + 5)(r - 7)
Therefore, Dimension of the rectangular rug will be (r + 5) × (r - 7)
