To do this problem, you will need to know the side lengths of the triangle. If you have those, just plug them in for a, b, and c and evaluate the square root.
Here is an example. If the sides are 3, 4, 5.
It would be:
The 6 is in the formula because it is the semi-perimeter (half).
Answer:
No, equivalent quarterly rate will be approx 1.75%
Step-by-step explanation:
Given that Chan deposited money into his retirement account that is compounded annually at an interest rate of 7%.
We know that there are 4 quarters in 1 year.
So to find that equivalent quarterly we will divide given yearly rate by number of quarters.
That means divide 7% by 4.
which gives 1.75%.
But that is different than Chan's though of 2% quarterly interest.
Hence Chan is wrong.

Answer:
Top and bottom= 12cm2
front and back= 36cm2
left and right= 24cm2
Surface Area = 72 cm2
Step-by-step explanation:
Top and bottom= 2×(3×2)12cm2
Surface Area = 2×(3×2 + 3×6 + 2×6) = 72 cm2
