Question

the area of a quarilateral triangle whose perimeter is 6cm is​

Answer 1

in equilateral triangle all sides are equal

let side of triangle=a

perimeter=a+a+a

6=3a

a=2cm

area=1/2×b×h

area=1/2×2×2

area=2cm²

Answer 2

Step-by-step explanation:

let the sides of triangle= x

perimeter of triangle= x+x+x

6cm= 3x

x= 6/3

x= 2cm

all side of triangle is 2cm

it is a equilateral triangle because it's all sides are equal

therefore,

area of triangle= √3a²/4

a= 2cm

√3(2)²/4

√3×4/4

√3cm

area of triangle= √3 cm
