Question

The length and width of a rectangle whose length is 10 centimeters more than its width

Answer 1

Surely you are being taught to first draw the rectangle, and label it.

My suggestion: label the width x, and label the length x + 10.

  

That appears to be all they have asked. But why don't you do this, for practice & understanding.

Write an algebraic expression for Perimeter.

Also write an algebraic expression for Area.

In your free time, you may color the rectangle any way you wish.
