Answer 2

Answer:

$\displaystyle 8\:inches\:wide \\ 18\:inches\:long$

Step-by-step explanation:

{wl = 144

{10 + w = l

w[10 + w] = 144

$\displaystyle w^2 + 10w - 144 \\ \\ [w - 8][w + 18]$

Since we are talking about DIMENSIONS, we ONLY want the NON-NEGATIVE root [8 = w, NOT −18 = w].

I am joyous to assist you anytime.
