Question

If the width of a rectangular piece of wood is x + 2 inches long and the length is three times as long with an additional inch added, what is the area of the wood?

Answer 1

If the width is x+2, and the length is 3 times the answer plus an inch then:

\[x+2\times3=3x+6\]

Then, just add an inch:

\[3x+6+1=3x+7\]

Your answer will be 3x+7 for the length.

Answer 2

For the area, you just multiply it and get:

\[x+2\times3x+7=3x ^{2}+14\]

I hope this helps!
