An isosceles trapezoid has bases of 4 and 10. If the base angle is 45°, the area = 1/2 x (4 + 10) x 3 = 21 square units.

The area of an equilateral triangle with a side of 6 inches is approx 15.59 square inches.

Area of Equilateral Triangle: K = (1/4) * sqrt 3 * a^2 = (1/4) * sqrt 3 * 6^2 = 15.59

Area of Equilateral Triangle: K = (1/4) * sqrt 3 * a^2 = (1/4) * sqrt 3 * 6^2 = 15.59
