We know that
lateral area=3*[area of a equilateral triangle]
Applying the law of sines to calculate the area of a equilateral triangle
Area=(1/2)*a*b*sin C
a=4
b=4
C=60 degrees
area equilateral triangle=0.5*4*4*sin 60-----> 0.5*4*4*√3/2---> 4√3 units²
lateral area=3*[4√3]----> 12√3 units²
the answer is
12√3 units²
Answer:
a
Step-by-step explanation:
when you times 5 by 2 you get 10 and 10 minus 6=4
20% greater = 1.2 times
so 10.2 x 1.2 is the answer. it is C.
