Question 1176018
<br>
Faulty problem description -- not enough information is given to answer the question.<br>
The vertices of the smaller triangle are the midpoints of the sides of the larger triangle.  From that, we know that the two triangles are similar, so the perimeter of the small triangle is half the perimeter of the large triangle.<br>
But the description of the problem doesn't tell us whether the longer of the two given sides is the longer leg of the larger right triangle, or it hypotenuse.  Therefore we can't determine the perimeter of the large triangle; and therefore we can't determine the perimeter of the small triangle.<br>
