13^2+169x

anonymous · Answer

How'd you get that answer?

anonymous · Answer

you don't want me to explain it it was confusing

anonymous · Answer

Nah, you just guessed.

anonymous · Answer

Oh well, we'll figure out if it was right or not.

anonymous · Answer

no i took 13 and squared it and then squared x because what you do to one side of the equation you have to do to the other and then i multiplied x to 169.

anonymous · Answer

The answer is the last option x^2+13x
Let breadth=x
Therefore Length=x+13
Area of a rectangle=Length*Breadth=(x)(x+13)=x^2+13x
