Answer:
223 ft²
Step-by-step explanation:
First, we need to find the scale factor. So, taking into account the lengths of the triangles, we get that the scale factor is:

Then, to know the area of the smaller triangle, we will use the following equation:

Where A2 is the area of the smaller triangle and A1 is the area of the larger triangle.
So, replacing k by 0.375 and A1 by 1583 ft², we get that the area of the smaller triangle is equal to:

Therefore, the answer is 223 ft²
