An architect plans to build an extension to​ Meiling's rectangular deck. Let x represent the​ increase, in​ meters, of her​ deck's length. The expression 3(8x+8) represents the area of the​ deck, where 3 is the​ width, in​ meters, and (x+8) represents the extended​ length, in meters. Use the Distributive Property to write an expression that represents the total area of​ Meiling's new deck.

To find the total area of Meiling's new deck, we need to multiply the width and the extended length. The width is 3 meters and the extended length is (x+8) meters. Using the distributive property, we can write the expression as:

3 * (x+8)

Expanding this expression, we get:

3x + 3 * 8

Simplifying further, we have:

3x + 24

Therefore, the expression that represents the total area of Meiling's new deck is 3x + 24 square meters.
