A kite in the shape of a square with each diagonal 36 cm and having a tail in the shape of an isosceles triangle of base 10 cm and equal side 6 cm, is made of three different shades as shown in the figure. How much paper of each shade has been used in it? [given,√11=3.3 1]
One shaded portion is ∆ABD.
∴Kite is the shape of square, so diagonals are equal and bisect each other
Second shaded portion is ∆BCD.
Third shaded portion is ∆CEF in which
CE = CF = 6 cm and EF -10 cm.
Here, a = 6 cm, b = 6cm andc = 10 cm
