Use the following ( a,b and c are the lengths of the 3 sides with a the longest side):-
If its acute then a^2 < b^2 + c^2
The object is to get everything except for "h" on one side of the equation.
The equation says that everything on the right side is being multiplied by 1/2.
What do we have to multiply times 1/2 to get 1? The answer is 2.
So multiply both sides by 2 to get rid of the fraction.
2A = (a+b)h
Now we are multiplying h times (a+b) so to get rid of (a+b) we have to divide both sides by that term.
(a+b)/(a+b) is 1
So you are left with: 2A/(a+b) = h
Done!

Answer:
What's the question?
Step-by-step explanation:
Answer:
20% increase
Step-by-step explanation:
Initial price: $2.25
New price: $2.70
Percentage=(new price - initial price)×100/(initial price)
p=(2.70-2.25)×100/2.25=45/2.25=20%
