Heron's formula is named after Hero of Alexendria, a Greek Engineer and Mathematician in 10 - 70 AD. You can use this formula to find the area of a triangle using the 3 side lengths.
Therefore, you do not have to rely on the formula for area that uses base and height. The picture below illustrates the general fro mu la where S represents the semi-perimeter of the triangle ,

<u>When we say to </u><u><em>solve for something</em></u>
<em> ⇒ essentially move everything to one side</em>
<em> ⇒ and that 'something' to the other</em>
<em />
In this case:
⇒ we need to move the y-variable by itself to one side
⇒ and everything else to the other
<em />
<u>Let's apply that principle</u>:

Answer:
300
Step-by-step explanation:
To find how many carrots, determine how many square units by finding the area. You can calculate the area by finding the area of the inside square 4 by 4 and then adding the area of each triangle on the side.
Area of square = 4*4 = 16 square units
Area of 2 triangles = 2(2*2*1/2)= 2(2) = 4 square units
16+4 = 20 square units.
15 carrots come from 1 square units so 15(20) = 300 carrots
P + 18 = 41
p = 41 - 18
p = 23
answer is C.
p + 18 = 41, p = 23
