Answer:
w² + 5w = Area
Step-by-step explanation:
The equation for an area of a rectangle is:
Length x Width = area
If w is the width, and length is 5 units longer than the width, then length can be classed as w + 5
Simply multiply these two values to find the area:
w + (w + 5) =
(w * w) + (w * 5)
w² + 5w = area
This is the area formula as no area has been given, nor can this be simplified.
