Answer:
The answer would be 1, whenever you square a negative number you should just input it as positive. The answer would be the same.
Step-by-step explanation:
Step 1
find the perimeter of a <span>single enclosure
perimeter of a square=4*b
where b is the long side of a square
area square=b</span>²
area square=2025 ft²
b²=2025-------> b=√2025-----> b=45 ft
<span>so
perimeter=4*45-------> 180 ft
step 2
</span>find the perimeter of a two individual enclosure
<span>perimeter=4*20+3*40------> 200 ft
area=20*40*2------> 1600 ft</span>²
<span>
therefore
fencing singular enclosure < fencing two individual enclosure
180 ft < 200 ft
</span>area singular enclosure > area two individual enclosure
2025 ft² > 1600 ft²<span>
the answer is the option
</span><span>a The singular enclosure would minimize cost because it requires 180 feet of fencing.</span><span>

Answer:
6.9
Step-by-step explanation:
An octagon has 8 sides so:
55.2=8*x
x=55.2/8=6.9
(-2, 4)
Hope this helps! If not I, truly sorry
Area of circle = πr² = 3.14×4² = 50.24m²
The best approximation is C.
