Question

if the perimeter of an equilateral is 24 cm then find its area​

Answer 1

Answer:

Step-by-step explanation:

In an eqilateral traingle all sides are equal. So

A + A+A= 24.......where a are sides

3A=24

A=8

Alll sides are 8 cm. Then area

=√3

____a sq

4

= √3

_____(8) sq

4

=√3

____ 8x8

4

=16√3 cm sq

Answer 2

Hey there!

Answer:

27.712 cm²

Step-by-step explanation:

Given,

Perimeter  = 24 cm

3 * side = 24 cm

side = 24/ 3

Side = 8 cm.

Now,

Area of eq. Δ = (√3 /4) * side²

                       = (√3 / 4) * 8 * 8

                        = √3 * 2 * 8

                        = √3 * 16

                        = 1.732 * 16

                        = 27.712 cm²
