Answer: 120 cm².

Step-by-step explanation:

1. To solve this problem you must apply the formula for calculate the area of a triangle, which is:

$A=\frac{b*h}{2}$

Where <em>b</em> is the base and <em>h</em> is the height of the triangle.

2. Then, when you substitute the values given in the problem you obtain:

$A=\frac{(4cm)(5cm)}{2}=10cm^{2}$

3. You know that the shape is made of 12 right triangle of equal size, therefore, multiply the area obtained by 12.

4. Then the area of the shape is:

$A_s=12(10cm^{2})=120cm^{2}$
