A kite in the shape of a square with a diagonal 32 cm and an isosceles triangle of base 8 cm and sides 6 cm each is to be made of three different shades as shown in figure. How much paper of each shade has been used in it?
It is given that ABCD is a square with cm. is isosceles with EF=8 cm and cm.
We know that diagonals of square are equal and bisect each other at .
Area of (1)
Area of =Area of (2)
Semi-perimeter of cm
Using Heron's formula, Area of
From (1), (2) and (3), we can say that
Area of region I=Area of region II=256
Area of region III=17.9
