Question

area of an equilant triangle is numerically equal to its perimeter. find a side of an triangle​

Answer 1

Answer:

Step-by-step explanation:

Let the side of an equilateral triangle is a

perimeter of equilateral triangle= area of equilateral triangle

3a= (√3/4)a^2

a= (4×3)/√3

a= (4×3)×√3/ √3×√3. ( by rationalising)

a= 4√3

side = 4√3

perimeter of equilateral triangle= 3a

perimeter of equilateral triangle= 3× 4√3

perimeter of equilateral triangle= 12√3

perimeter of equilateral triangle= 12× 1.732

perimeter of equilateral triangle= 20.78 units

[ value of √3 = 1.732]
