Find the area of a quadrilateral ABCD in which AD = 24 cm, ∠BAD = 90° and BCD forms an equilateral triangle whose each side is equal to 26 cm. (Take √3 = 1.73)
Given that, a quadrilateral ABCD in which AD = 24 cm, ∠BAD = 90° BCD is equilateral triangle and sides BC = CD = BD = 26 cm
In ∆BAD By using Pythagoras theorem
