Question

it is given that √3= 1.732. The area of an equilateral triangle with side 4√3 cm is ​

Answer 1

Answer:

20.78

Step-by-step explanation:

side of equilateral triangle=a=4√3

ar of equilateral triangle-

√3/4 * a^2

=√3/4 *(4√3)^2

=20.78

Answer 2

Answer:

the area of the triangle is =  20.784 $cm^2$

Step-by-step explanation:

Given :

We are given that the side of the equilateral triangle = $4\sqrt3$ cm

To Find :

the area of equilateral triangle  =  ?

Solution :

We are given that the the side of the equilateral triangle = $4\sqrt3$ cm

We have to find the area of the triangle

Since we know that the area of a equilateral triangle = $\frac{\sqrt3}{4}a^2$ where a is the side of the triangle

the the area of the equilateral triangle  = $\frac{\sqrt3}{4}({4\sqrt3})^2$ ${cm}^2$

                                                                  = $\frac{\sqrt3}{4}(48)$

                                                                  = $\sqrt 3 \ \text{x} \ 12$

                                                                  = 1.732 x 12

                                                                  =  20.784 $cm^2$

Therefore the area of the triangle is =  20.784 $cm^2$
