Give me a detailed explanation​

Answer 1

Answer:

For an equilateral triangle with side ‘a’, area

∴ Each side of the triangle = a cm

∴ a + a + a = 180 cm

⇒ 3a = 180 cm

Now, s = Semi–perimeter

∴ Area of a triangle

∴ Area of the given triangle

Thus, the area of the given triangle

Answer 2

Step-by-step explanation:

First let us prime factorise 13824:

13824 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3

= 2^3× 2^3× 2^3× 3^3

3√13824 = 2 × 2 × 2 × 3 = 24
