Area of a Rectangle Calculator
This Area of a Rectangle Calculator helps you find the space inside a rectangle when the width and length are known. It uses the formula A = w × l, where w is the width, l is the length, and the answer is written in square units. Multiply the width by the length to get the area. It is a simple way to check answers, understand the rectangle area formula, and practise basic geometry step by step.
In the diagram, the width is w and the length is l.
Step-by-step method
- Identify what is given.
- Write the formula.
- Substitute the values and calculate the area.
Formula:
Example 1:
Step 1 - Identify what is given.
In this problem: The given dimensions are \(w = 5\) and \(l = 3\).
Step 2 - Write the formula.
In this problem: Use the rectangle area formula: \(A = wl\).
Step 3 - Substitute the values and calculate the area.
In this problem: Substitute \(w = 5\) and \(l = 3\): \(A = 5 \times 3 = 15\).
Final answer:
Example 2:
Step 1 - Identify what is given.
In this problem: The given dimensions are \(w = 7.5\) and \(l = 2\).
Step 2 - Write the formula.
In this problem: Use the rectangle area formula: \(A = wl\).
Step 3 - Substitute the values and calculate the area.
In this problem: Substitute \(w = 7.5\) and \(l = 2\): \(A = 7.5 \times 2 = 15\).
