Answer:
Option C. 1400 ft
Step-by-step explanation:
we know that
In a Front End Estimation we keep only one number in the front and all the others became zeros
The perimeter of a rectangular area is equal to
[tex]P=2(L+W)[/tex]
where
L is the length and W is the width
we have
[tex]L=432\ ft\\W=345\ ft[/tex]
Applying front-end estimation
we have
[tex]432\ ft=400\ ft\\345\ ft=300\ ft[/tex]
Find the perimeter
[tex]P=2(400+300)[/tex]
[tex]P=1,400\ ft[/tex]
