#The Area = 230.04 units^2 #

First we would find S which is the sum of the 3 sides divided by 2.

#S = (29 + 21 + 22)/2 # = #72/2# = 36

Then use Heron's Equation to calculate the area.

#Area = sqrt(S(S-A)(S-B)(S-C)) #

#Area = sqrt(36(36-29)(36-21)(36-22)) #

#Area = sqrt(33(7)(15)(14)) #

#Area = sqrt(52,920) #

#Area = 230.04 units^2 #
