To solve this exercise you must follow the proccedure shown below:

 1. You have the the lengths of the sides of equilateral triangle which is inscribed inside a similar triangle are 10 cm. Therefore, the area is:

 A1=bxh/2
 A1=10 cmx10 cm/2
 A1=50 cm²

 2. <span>The larger triangle is dilated with a scale factor of 3 from the smaller triangle. Using the ratio of the area:

 (1/3)</span>²<span>=50/A2
 1/9=50/A2
 A2=450 cm</span>²
<span>
 3. The area of the shaded region is:
