Let

using a graph tool
see the attached figure
The figure is a triangle
we know that
<u>The Heron's Formula</u> is a method for calculating the area of a triangle when you know the lengths of all three sides.
Hero's Formula is equal to

where
p is is half the perimeter of the triangle
a,b,c are the lengths of the sides of a triangle
so
Step 
<u>Find the length sides of the triangle</u>
a) <u>Find the distance AB</u>

Substitute


b) <u>Find the distance AC</u>

Substitute


c) <u>Find the distance BC</u>

Substitute


Step
<u>Find the perimeter of the triangle</u>

<u>Find the half of the perimeter </u>

Step 
<u>Find the area of the triangle</u>



therefore
<u>the answer is the option </u>
a) 1.65 mi^2.
Answer:
The answer is <u>B.) $16</u>
Step-by-step explanation:
Multiply 16$ by 6 which resembles half a year. You will get $96 from 16*6
Answer: 126
Step-by-step explanation: substitute c for 41 and simplify
Answer: $55.35
Step-by-step explanation:
if the bill is $46.15, round it up to $46. Twenty percent of that is $9.20, found by moving the decimal point one place left. Add $9.20 to $46.15, and you get $55.35
i hope this is correct and it helps :)
