Answer:
86 units squared.
Step-by-step explanation:
If the perimeter is 30 and it is an equilateral triangle, the means each side of the triangle is equal so they must all be 10 units longs. Since the line XA is part of the quadrilateral, lines FL and XA of the rectangle must be 10 units long. But we still don't know the length of the sides. Within the box are two right triangles, FZX and ZLA. We know the the length of the hypotenuse which is 10 units, and the base which is 5 units. Then we use the Pythagorean Theorem so find the length of the sides. After we do that we get about 8.6. Now we can multiply the length and width to get an area of 86.
Your awnser is a because 192x6=1152.
