Find the area of a rectangle whose length is 7 cm and breadth is 4 cm. Which of the following is correct?

Step-by-step solution

1. Step 1: Write the formula for area of a rectangle: $A=\text{length}\times \text{breadth}$ because area is the product of its sides.
2. Step 2: Substitute the given lengths into the formula: $A=7\text{ cm}\times 4\text{ cm}$.
3. Step 3: Multiply the numbers: $7\times 4=28$.
4. Step 4: State the area: $28{\text{ cm}}^2$ is the area of the rectangle.
