Show Worked Solution
\(\text{Method 1: Subtraction}\)
| \(\text{Area}\) | \(=\text{Area of large rectangle}-\text{Area of cut-out rectangle}\) |
| \(=(10\times 6)-(8\times 2)\) | |
| \(=44\ \text{cm}^2\) |
\(\text{Method 2: Addition}\)
| \(\text{Area}\) | \(=\text{Area of large rectangle}+\text{Area of small rectangle}\) |
| \(=(10\times 4)+(2\times 2)\) | |
| \(=44\ \text{cm}^2\) |
