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 ,

Let width = x ft then
2x + 2(2x) = 42
6x = 42
x = 7
so the width is 7 ft and length is 14 ft.
So the cost to build the pen = 14*1.25 + 14*1,25 + 7*2.50 + 7*2.50
= 70 answer
Answer:
x = 1
Step-by-step explanation:
First simplify and get 3x + 3 = x + 5
Then subtract x from both sides and get 2x + 3 = 5
Then subtract 3 from both sides and get 2x = 2
Divide both sides by 2 and get x = 1
Answer:
