- area of triangle =1/2×b×h
- 216cm^2=1/2×24×h
- h=(2×216)/24=18cm
- 3rd side=sqrt of (18^2)+(24^2)
- = 324+576
- =sqrt of 900=30cm
- perimeter =24+18+30=72cm

area of triangle = 1/2 x b x h
216 = 1/2 x 24 x h
216 = 12h
h = 216/12
h = 18...
AC²= BA² +BC²
AC² = 24 ² + 18²
AC =√ 576 + 324
AC = √900
AC = 30
perimeter = sum of all sides
p = 24+18+30
p = 72....
hope it help you
