(instant asap) a canvas pennant is in the shape of an equilateral triangle. if each side of the pennant measures 16 inches, what is the area of the pennant? a.111 b.128 c.232 d.256

For this case, the area is given by:
 A = root ((s) * (s-a) * (s-b) * (s-c))
 Since the triangle is equilateral then:
 a = b = c = 16
 On the other hand,
 s = (a + b + c) / 2
 s = (16 + 16 + 16) / 2
 S = 24
 Substituting values:
 A = root ((24) * (24-16) * (24-16) * (24-16))
 A = 110.8512517
 Rounding off we have:
 A = 111
 
 the area of the pennant is:
 A.111

This is too long-standing now get out
