Answer:
x=14 y=-3
Step-by-step explanation:
17 x .12 = 2.04 is the answer
Using the law of sines to solve the triangle if..
The area of a rectangle can be found by multiplying the length times the width, or A = l * w. The perimeter of the rectangle can be found by adding together the length twice and the width twice. From the given information, we know that l = p and w = p + 4, where l represents the length of the rectangle and w represents the width of the rectangle.
A = l * w = p(p+4) = p^2 + 4p
P = 2l + 2w = 2(p) + 2(p+4) = 2p + 2p + 8 = 4p + 8
Therefore, the area of the rectangle is p^2 + 4p and the perimeter of the rectangle is 4p + 8.
Hope this helps!
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
