A) log (33)
B) log (7/9)
Use the log addition and subtraction rule
Answer:
The formula of area is Pi×R×R
and then you add all sides and answer of your question is 30cm
Let S be the first side.
Longest side is then 2S.
Third side is 2S-10.
Perimeter is sum of all three sides = S+2S+2S-10 = 75
=>
5S-10=75
5S=75+10=85
S=17
Therefore
S=17 is the first side.
Longest side is then 2S=2*17=34.
Third side is 2S-10=2*17-10=24.
