Question

The perimeter of an equilateral triangle is 60 m. What will be its area?​

Answer 1

Answer:

Let each side of an equilateral be x.

Let each side of an equilateral be x.Then, perimeter of an equilateral triangle = 60 m

Let each side of an equilateral be x.Then, perimeter of an equilateral triangle = 60 mx + x + x = 60 ⇒ 3x = 60 ⇒ x = 60/3 = 20 m

Let each side of an equilateral be x.Then, perimeter of an equilateral triangle = 60 mx + x + x = 60 ⇒ 3x = 60 ⇒ x = 60/3 = 20 mArea of an equilateral triangle = √3/4 (Side)2 = (√3/4) x 20 x 20 = 100 √3 m2

Let each side of an equilateral be x.Then, perimeter of an equilateral triangle = 60 mx + x + x = 60 ⇒ 3x = 60 ⇒ x = 60/3 = 20 mArea of an equilateral triangle = √3/4 (Side)2 = (√3/4) x 20 x 20 = 100 √3 m2Thus, the area of triangle is 100√3 m2.

Answer 2

Step-by-step explanation:

p=60m.

3a=60

side((denoted by a))=60/3=20.
