Use geometric shapes, measurements, and properties to describe real-world objects.
Compute exact and two-decimal modeled area
Problem
Calculate the area of a rectangular tabletop measuring \(6~\text{ft}\) by \(3~\text{ft}\). Show the formula substitution, exact area, and area to \(\text{two}~\text{decimal}~\text{places}\) with correct units.
Big Picture
What this problem is really about
Translate the real object into its planar model, then use the area formula that matches that shape. Multiplying two perpendicular lengths also multiplies their units, so the result must be expressed in square units rather than linear units. Keep the exact calculation visible, and treat the requested two-decimal form as a precision format for that same area.
