Answer 1

Answer:

Use the perimeter to find the sides of the triangle (3x + 10 = 100). Then use half the largest side and one of the equal sides to find the height through the Pythagorean Theorem. Finally, use the newly found height and the largest side of the triangle as its base in the formula to find a triangle's area.
