Question

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 each 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? [Take V11 = 3.31] ​

Answer 1

Answer:

kite is in a poop shape kaksa

Answer 2

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

Area of triangle CFE

s=(6+6+10)/2

s=11cm

=√s(s-a)(s-b)(s-c)

=√11(11-6)(11-6)(11-10)

=√11*5*5*1

=5√11

=5*3.31

=16.55cm^2
