Answer:
Number 4
Step-by-step explanation:
The formula for a right rectangular prism is width*height*length
The equation that could be used to determine L, the unknown side length of the logo is A =2.5w
<h3>How to determine the equation?</h3>
The given parameters in the question are:
- Shape: Rectangle
- Height of logo, h = 2 1/2 feet
From the question we understand that the area is at maximum.
Represent this area with A
The area of the rectangle is:
A = h * l
Where h and l are the dimensions of the rectangle.
Substitute 2 1/2 for h
A = 2 1/2 * l
Express 2 1/2 as a decimal number
A = 2.5 * l
Evaluate the product
A =2.5l
Hence, the equation that could be used to determine L, the unknown side length of the logo is A =2.5w
