Here we are given the three sides of the triangle.
So we have Heron's formula to find its area.
Heron's formula is given by :
where A, B and C are sides of triangle and S is semi perimeter which is given by,
plugging values of A, B and C to find S
S=18
Now plugging values of A, B , C and S in Heron's formula
A=46.48 m²
Answer: Area of triangle is 46.48 m².
Let the number of hours Paul needs to work = h.
You need to multiply Paul's hourly rate by the number of hours (h) to either be equal to or greater than what Alan makes:
The equation would be:
8.25h ≥ 363
To Solve divide both sides by 8.25
h ≥ 363 / 8.25
h ≥ 44
Paul needs to work at least 44 hours
Answer: 8.55 minutes.
Step-by-step explanation: To find the time to run a mile, divide the total minutes by the total number of miles.
94/11=8.55
It will take 8.55 minutes to run one mile.
