Answer:
Step-by-step explanation:
Area = 0.5(base)(height)
= 0.5(16.9)(10.4)
= 87.88 sq ft
<span> sqrt (2160x8)(60x2) =
12 x4 • sqrt(15)
</span>
<span> 12 x4 • sqrt(15) </span>
Answer:32
Step-by-step explanation:
Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft
Answer:
I think that x equals 10 (maybe)
