The sum of a long side and short side will be half the perimeter, so the long side has length (70/2) -16 = 19 cm.
The other three sides are 16 cm, 19 cm, 19 cm.
Answer:
23
Step-by-step explanation:
The √125 can be factored out to 25 and 5 then 25 can be factored out to 5 and 5. Then you pair up the numbers, you have a pair of 5's and a 5 left over. So the pair of 5's goes inside the radical as √5 and on the outside of the radical you have 5×3. So 3√125≈15√5.
For example on -9+6 you would start at -9 and go right 6 times over and what you land on is your answer<span />
