1.	2 The area of an equilateral triangle is numerically equal to its perimeter.Find a side of the triangle [Take 3 1-73].
Answer» Let the side of an equilateral triangle is a perimeter of equilateral triangle= area of equilateral triangle 3a= (√3/4)a^2a= (4×3)/√3a= (4×3)×√3/ √3×√3. ( by rationalising)a= 4√3side = 4√3= 4×1.73=6.92

Answer»

Let the side of an equilateral triangle is a

perimeter of equilateral triangle= area of equilateral triangle

3a= (√3/4)a^2a= (4×3)/√3a= (4×3)×√3/ √3×√3. ( by rationalising)a= 4√3side = 4√3= 4×1.73=6.92
