Question

4. The area of the equilateral triangle is 206 cm 2 whose each side is 8 cm​

Answer 1

Answer:

Area of an equilateral triangle of side a = √3/4

${a}^{2}$

According to the question,

Area of a triangle = 20√3

${cm}^{2}$

⇒ √3/4 a2 = 20√3

⇒ a2 = 20× 4

⇒ a2 = 80

⇒ a = 4√5 cm

Hence, the statement “the area of the equilateral triangle is 20√3 cm2 whose each side is 8 cm” is False.
