Question:

Ella has a rectangular garden that is 20 feet longer than it is wide. A: What would be the equation that represents the length if the width is x? B: What would the algebraic equation for the perimeter be?

Answer:

A: if the width is equal to x, and the length is 20 feet longer than the width, then the length is (x+20). B. The equation for the perimeter of a rectangle is 2l+2w=P. If l=x+20, then 2(x+20)+2(x)=P. This can be simplified: 1. Distribute: 2x+40+2x=P 2. Add like terms: 4x+40=P
