Question

$5\times10=(4\times6)+(5\times6)$
$=\underline{\quad\quad}+\underline{\quad\quad}$
$area=\underline{\quad\quad}$

Explanation:

Step1: Split shape into 3 rectangles

The figure is split into: top rectangle ($4\text{cm} \times 5\text{cm}$), middle rectangle ($1\text{cm} \times 10\text{cm}$), bottom rectangle ($6\text{cm} \times 5\text{cm}$).

Step2: Calculate each rectangle's area

Top area: $4 \times 5 = 20\text{cm}^2$
Middle area: $1 \times 10 = 10\text{cm}^2$
Bottom area: $6 \times 5 = 30\text{cm}^2$

Step3: Sum all areas

Total area = $20 + 10 + 30$

Answer:

$60\text{cm}^2$
