Question

the area of
a of an isosceles triangle each of whose equal sides is 13 cm
and whose base is 24 cm is
(a) 45cm
(b) 48cm
(c) 60cm
(d) 75cm​

Answer 1

Answer:

Option c is the right answer.

Answer 2

Answer:

(c) 60 sq cm

Step-by-step explanation:

Perimeter of triangle = 24 + 13 + 13 = 50 cm

Half perimeter = 25

Using Heron's formula

Area = √(25(25 - 24)(25 - 13)(25 - 13))

         =√(25*1*12*12)

         =√(5²*12²)

         =  5*12 = 60

Area = 60 sq cm
