Question

Find area of triangle if perimeter is 24?

Answer 1

the perimeter of a 3 equal triangle is 3x

where x is the side lenth.

so 3x= 24 cm

x =8 cm

hence ,each side length is 8cm

here comes its area

Equilateral triangle area=

(square root of 3)/4xsqare cm square

now put the value of x

gives (root 3)/4*8sqare

=(root 3)/4*64

=(root 3)*16 cm square

hence[16 root 3] cm square is the area of an equilateral triangle with each side length 8cm

square is = 2
