Each of the equal sides of an isosceles triangle is 13cm and base is 24cm. The area of the triangle is –

It is given in the question that,

Equal sides of isosceles triangle = 13cm

Base = 24 cm and = 12 cm

Let the height of the triangle be h

∴ (13)^{2} = (12)^{2} + h^{2}

169 = 144 + h^{2}

h^{2} = 169 – 144

h^{2} = 25

h = 5

Thus, area of triangle =

=

=

= ^{2}

Hence, option (c) is correct

14
