What is a perimeter of an equilateral triangle, if each*side of a tria

1.	What is a perimeter of an equilateral triangle, if each*side of a triangle is 5 \(\frac {3}{10}\) cm?
Answer» Let the side of an equilateral triangle be x cm. Perimeter of an equilateral triangle = 3x. = 3 × 53/10 = 3/1 x 53/10 = \(\frac {3\times53}{1\times10}\) ∴ Perimeter of triangle = \(\frac {159}{10}\) or \(5\frac{9}{10}\) cm

What is a perimeter of an equilateral triangle, if each*side of a triangle is 5 \(\frac {3}{10}\) cm?

Answer»

Let the side of an equilateral triangle be x cm.

Perimeter of an equilateral triangle = 3x.

= 3 × 53/10

= 3/1 x 53/10

= \(\frac {3\times53}{1\times10}\)

∴ Perimeter of triangle = \(\frac {159}{10}\) or \(5\frac{9}{10}\) cm
