A project manager is calculating the floor area of a square office space where each side has a length of $m + 4$ feet. To find the total area, the manager needs to expand the expression $(m + 4)^2$. Which of the following is the correct trinomial expansion for this area?

A landscape architect is calculating the area of a square garden plot with a side length of $m + 4$ feet. To expand the area expression $(m + 4)^2$ using the standard algebraic pattern, arrange the following steps in the correct order.

A construction site manager is expanding a square storage area with a side length of $m + 4$ meters. To calculate the total floor area, the manager expands the expression $(m + 4)^2$ into the trinomial $m^2 + 8m + 16$. Match each term of this resulting trinomial to the specific calculation step used to find it.

A solar energy technician is installing a square solar panel with a side length of $m + 4$ decimeters. To find the total surface area, the technician expands the expression $(m + 4)^2$. According to the standard algebraic pattern for squaring a binomial, the constant (numerical) term in the resulting trinomial is ____.

A facilities manager is calculating the floor area of a square conference room where the side length is represented by the expression $m + 4$ meters. To find the total area, they expand the formula $(m + 4)^2$ and conclude that the expanded expression is $m^2 + 16$ square meters.
