Question

Perimeter =24
If an equilateral triangle has a perimeter of 24 cm. then find the area of the triangle
using Heron's formula.






Ans:
Perimeter=24
24/3=8cm

semi perimeter=24/2=12
$\12(12 - 8)(12 - 8)(12 - 8)$
$\sqrt{12(4)(4)(4)}$
$2 \times 2 \times 2 \times 2 \times 2 \sqrt{3}$
16√3​

Answer 1

Answer:

Perimeter of equilateral triangle = 24cm

( there are three equal sides in an e

quilateral triangle )

Each side = 24 / 3 = 8cm

Area of an equilateral triangle = root 3 / 4 s square

= root 3 / 4 × 8 square

= root 3 / 4 x 64

= root 3 × 16

= 16 root 3
