Find the area of a triangle with a =4, b =6, and c =8.
a. 10.2 units 2
b. 8.4 units 2
C.12.4 units
d. 11.6 units 2

d

Step-by-step explanation:

Given 3 sides of the triangle the area (A) can be calculated using Hero's formula.

A =

where s is the semi perimeter of the triangle

s = = = = 9 , thus

A =

   =

   =

   ≈ 11.6 units² → d

other answer is correct. i had used the radius of the radius somehow. a website:

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
