Answer:
A
Step-by-step explanation:
The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is 
where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.
This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.

Step-by-step explanation:
In getting the area of and equilateral triangle, you must first consider that all of its sides are congruent and that is 3 inches, so the formula in getting the area is height form its base so in getting its height you must use the pythagorean theorem by dividing the triangle so the hypotenuse of it is 3 and the base of 1.5inches, so the height is 4.77 inches then the area is 7.15 sqr.inch
Are you sure your in high school, also it's answer #3.
