Question

A traffic signal board, indicating’ SCHOOL AHEAD’ , is an equilateral triangle with side ‘a’ .Find

the area of the signal board, using Heron’s Formula . If its perimeter is 180 cm, what will be the area

of the signal board?

What value is depicted in the question?...
​

Answer 1

Step-by-step explanation:

Perimeter=180

Hence, equilateral triangle all sides are equal.

A+a+a=180

A=60

Herons formula area =

$\sqrt{s \times (s - a )\times (s - b) \times (s - c)$

Area =1558.8 Sq. M
