The question consists of two statements namely, Assertion (a) and Reason (R). Please select the correct answer.
Assertion (A) | Reason (R) |
The area of an isosceles triangle having base = 24 cm and each of the equal sides equal to 13cm is 60cm^{2}. | If 2s = (a + b+ c) where a, b, c are the sides of a triangle, then area = . |
From the given question, we have
a = 24 cm, b = 13 cm and c = 13 cm
∴ s =
=
=
= 25 cm
Now, by using heron’s formula we have:
Area of triangle =
=
=
= 5 × 12
= 60 cm^{2}
Also, if 2s = (a + b + c) where a, b and c are the sides of the triangle then:
Area =
∴ Assertion and reason both are correct
Hence, option (a) is correct
