Answer: Width = 9 inches

Length = 12 inches

Step-by-step explanation: A = (w+3)(w)

A = w2 + 3w = 108

w2 + 3y - 108 = 0

This is the factor of the problem: (w - 9) (w + 12) = 0

This equals to w + 12 = 0

w = -12

Then the final answer would be Width = 9 inches

Length = 12 inches.

Hope this helps!

Answer:

That would be the side-side-side (SSS) postulate, which states that if all the sides of a triangle are in a fixed ratio to all the corresponding sides of another triangle, then the two triangles are said to be congruent.

Step-by-step explanation:

Looking at triangles ABC and DEF, we notice that:

$\frac{AB}{DE} = \frac{AC}{DF}=\frac{BC}{EF}$

since

$\frac{3}{18} = \frac{6}{36}=\frac{7}{42}=\frac{1}{6}$
