Question

choose the correct unit for each measurement. then write your answer.
linear units square units cubic units
1a. the area of the surface of a table
1b. the perimeter of a fenced - in field
1c. explain your answer choices. include a sketch in your explanation.

Explanation:

• For 11a: Area measures the amount of space on a 2 - dimensional surface. Square units are used for 2 - D measurements like the surface of a table. For example, if the table is a rectangle with length \(l\) and width \(w\), the area \(A = l\times w\), and the result is in square units (e.g., square feet \(ft^{2}\) if \(l\) and \(w\) are in feet).
• For 11b: Perimeter is the total length around a 2 - dimensional shape. Linear units measure length. If the fenced - in field is a rectangle with length \(l\) and width \(w\), the perimeter \(P=2(l + w)\), and the result is in linear units (e.g., feet \(ft\) if \(l\) and \(w\) are in feet).

Answer:

11a. square units
11b. linear units
