Step-by-step explanation:
The area (A) of a triangle using Heron's formula is
A = 
where s is the semiperimeter and a, b , c the sides of the triangle.
s = 
= 
= 
= 4.5
Then
A = 
= 
= 
≈ 1.9843...
= 2 ft² ( to the nearest square foot )
Answer:
x = 57

x = 57
To convert yards to feet, you would multiply it by 3. So, since there the pipe is 2 yards long, you could multiply 2*3 to get 6 feet. Then you can convert feet to inches by multiplying it by 12. 6*12 is equal to 72, so 2 yards is equal to 72 inches. Lastly, you can subtract 18 from 72, to get 54, and 54 inches would be your final answer.
