Answer:
d) 24.2 cm²
<em>Area of equilateral triangle A = 24.22 cm²</em>
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
<em> Perimeter of equilateral triangle = 3 a</em>
Given Perimeter of equilateral triangle = 22.45 cm
now 3 a = 22.45
Dividing '3' on both sides,we get
a = 7.48 cm
<u><em>Step(ii):</em></u>-
<em>Area of equilateral triangle</em>
<em> </em><em></em>
<em> </em><em></em>
<em> A = 24.22 cm²</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>Area of equilateral triangle A = 24.22 cm²</em>
