Question

The area of a rectangular rug is give. By trinomi r^2-2r-35 what are possible dimensions of the rug

Answer 1

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)
