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

1. Identify what is given.
2. Write the formula.
3. Substitute the values and calculate the area.

Formula:

Example 1: w = 4, l = 6

Step 1 - Identify what is given.

In this problem: The given dimensions are w = 4 and l = 6.

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 = 4 and l = 6: A = 4 × 6 = 24.

Final answer: A = 24

Example 2: w = 3.5, l = 2

Step 1 - Identify what is given.

In this problem: The given dimensions are w = 3.5 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 = 3.5 and l = 2: A = 3.5 × 2 = 7.

Final answer: A = 7
