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
Please provide more information. You need to add the sides of the polygon to find the perimeter.
Answer: 22
Step-by-step explanation:
I’m not sure if hats number is a 5.50 but if it is the answer would be 22 I think ^^ I might be wrong?
The area of a trapezoid is given by
.. A = (b1 +b2)/2*h
.. = (13 cm +21 cm)/2*(6 cm)
.. = 102 cm^2 . . . . . . . . . . . . . . corresponds to selection A
