The reduction was 1/5.
Because you are given the reduced values, multiply the reduced value by the inverrse of the factor:
Inverse of 1/5 = 5
Height = 3 x5 = 15
Base = 5 x 5 = 25
The base is 25
I think the answer is B im not sure :(
7 + 3 = 10 those are the 2 addens
100.47 because: 33.3+1.4 =34.7
785+1=786
34.7log(786)=100.47
