A regular pentagon and a rectangle have the same perimeter. The width of the rectangle is 10 more than its length. The length of the rectangle and the side of the pentagon are equal. What can be concluded about what is needed to write an equation? Check all that apply.
If we use the variable l for length, then the width is l + 10.
If we use the variable w for width, then the length is w + 10.
A key phrase is “same perimeter.”
A key word is “equal” when referring to the length of the two shapes.
A key word is side.
