1.	Perimeter of an equilateral triangle is 36 cm. Find its area using Heron's formula
Answer» ANSWER: let one side be "a" a + a + a = 36 3a = 36 a = 36/3 a = 12 cm. Now, if we APPLY Herons Formula, 12 + 12 + 12/2 = 18. ( 18 is the semi - perimeter) (18- 12) (18-12) (18-12) 6 X 6 X 6 2X3X2X3X2X3 2X2X3X3 root 2X3 (We consider both pairs of 2X2 as one) 6 root 6 is your answer.

ANSWER:

let one side be "a"

a + a + a = 36

3a = 36

a = 36/3

a = 12 cm.

Now, if we APPLY Herons Formula,

12 + 12 + 12/2 = 18. ( 18 is the semi - perimeter)

(18- 12) (18-12) (18-12)

6 X 6 X 6

2X3X2X3X2X3

2X2X3X3 root 2X3

(We consider both pairs of 2X2 as one)

6 root 6 is your answer.
