Question

The perimeter of a triangle ABC is 41.36cm. Find the area of triangle ABC.

Answer 1

Hello thanks us for asking a question.

Area of triangle  = 1/2 × Base × Height

Area of triangle  = √[s ( s − a )( s − b )( s − c )],

2s  = a + b + c

 perimeter  =  41.36 cm 

Sides of equilateral triangle  = 41.363 / 3 =  13.78 cm 

And Area of equilateral triangle  = √3/4×(Side)²

Area of equilateral triangle  = √3/4×(13.78)2

= 82.22 cm2
