Final answer:
To find the missing measurement, use the formula for the area of a rectangle: Area = Length × Width. Substitute the known values for the area and width, and solve for the missing length. The correct answer is a) 6.6 m.
Step-by-step explanation:
To find the missing measurement, we need to determine which measurement is missing. The given measurements are a) 6.6 m, b) Area = 18.5 m², c) Height = 3.0 m, and d) Width = 2.8 m. Since we are asked to find the missing measurement, let's locate which measurement is missing from these options. The missing measurement is the length of the rectangular room, which is not provided. Therefore, the missing measurement is the length.
To calculate the missing length, we can use the formula for the area of a rectangle: Area = Length × Width. We know the area is 18.5 m² and the width is 2.8 m. Substituting these values into the formula, we can solve for the missing length. Length = Area ÷ Width = 18.5 m² ÷ 2.8 m = 6.6071 m. Rounding to the nearest tenth, we get 6.6 m as the missing length.
Therefore, the correct answer is a) 6.6 m.
