An equilateral triangle has an apothem measuring 2.16 cm

Llana [10]

Answer:

d) 24.2 cm²

Area of equilateral triangle A = 24.22 cm²

Step-by-step explanation:

Step(i):-

Perimeter of equilateral triangle = 3 a

Given Perimeter of equilateral triangle = 22.45 cm

now 3 a = 22.45

Dividing '3' on both sides,we get

a = 7.48 cm

Step(ii):-

Area of equilateral triangle

$A = \frac{\sqrt{3} a^{2} }{4}$

$A = \frac{\sqrt{3} (7.48)^{2} }{4}$

A = 24.22 cm²

Conclusion:-

Area of equilateral triangle A = 24.22 cm²
