Question

the perimeter of an equilateral triangle is 48 centimetre its area is​

Answer 1

Answer:

Area of the given equilateral triangle is 6.92 cm sq units

Step-by-step explanation:

Given that perimeter of the equilateral triangle is 48 cm.

Now,

Perimeter of equilateral triangle is 3a, where 'a' is the side of triangle.

Therefore,

3a=48

a=48/3

Thus,

a=16 cm.

Now,

Area of the equilateral triangle is

√3a/4.

Thus,

A(area of the equilateral triangle)

= √3(16)/4

=4√3.cm Sq units.

If we consider √3 value i. e., 1.73

We get area of triangle as 6.92 cm Sq units.
