The area of the patio is 216 square feet. Write an equation that represents the area of the patio
Hoochie [10]

Answer:

216=2w \times w

Step-by-step explanation:

Assuming that the patio is a rectangle, we have

A= l\times w

Where l is the length and w is the width.

Now let's assume that the length of the patio is double than the width.

l=2w

So, the equation that represents this problem is
