Question

find the area of equilateral triangle whose sides are 16dm​

Answer 1

Area of equilateral triangle

= √3/4a²

= √3/4×16²

= √3/1024

Answer 2

Answer:

Area = 110.85 dm²

Step-by-step explanation:

Area of equilateral triangle = $\frac{\sqrt{3} }{4} a^{2}$

a = 16 (given)

Area = $\frac{\sqrt{3} }{4} (16)^{2}$

        = $\frac{\sqrt{3} }{4}$ x 256

        = 110.85 dm²
