A kite in the shape of a square with a diagonal 32 cm and an isosceles triangles of base 8 cm and sides 6 cm each is to be made of three different shades as shown in the given figure. How much paper of each shade has been used in it?

We know that

Area of square (diagonal)2

Area of the given kite

Area of 1st shade = Area of 2nd shade

Therefore, the area of paper required in each shape is 256 cm2.

For IIIrd triangle


By Heron’s formula,

Area of triangle

Area of IIIrd triangle

Area of paper required for IIIrd shade = 17.92 cm2
