What is the area of a rectangular field with sides 19.5 m and 15.8 m?
Answer (2)
Identify the rectangle's length and width.
Apply the area formula: A = l × w .
Calculate the area: A = 19.5 × 15.8 = 308.1 .
State the final answer: 308.1 m 2 .
Explanation
Problem Analysis We are given a rectangular field with sides of length 19.5 m and 15.8 m. We need to find the area of this field.
Area Formula The area of a rectangle is given by the formula: A = l w where A is the area, l is the length, and w is the width. In our case, l = 19.5 m and w = 15.8 m.
Calculation Now, we substitute the given values into the formula: A = 19.5 × 15.8 A = 308.1 The area is 308.1 square meters.
Final Answer Therefore, the area of the rectangular field is 308.1 square meters.
Examples
Understanding the area of a rectangle is useful in many real-life situations. For example, if you're planning to build a rectangular garden, knowing the area helps you determine how much soil you need to buy. Similarly, when tiling a rectangular floor, the area tells you how many tiles are required to cover the entire surface. These calculations ensure you purchase the right amount of materials, saving both time and money.
The area of the rectangular field is calculated by multiplying its length (19.5 m) by its width (15.8 m), which gives an area of 308.1 square meters. Therefore, the final answer is 308.1 m².
