Answer:
(z, v)
Step-by-step explanation:
When the sides of the rectangle align with the axes, as here, the coordinates will be all (x, y) combinations from the sets x ∈ {w, z) and y ∈ {v, z}. Three of those combinations are shown. The fourth is (z, v).

Answer:
= 52sqrt3
Step-by-step explanation:
Area of a trapezium is given by the formula;
1/2(a+b)h
Where a and b are the parallel sides and h is the perpendicular height.
a = 15 ft, b= 11 ft and h = 4√3
Therefore;
Area = 1/2 (15+11) 4√3
= 1/2 × 26 × 4√3
= 52√3 ft²
Answer:
Maximum area possible
f(max) = 3906,25 ft²
Dimensions:
a = 62,5 ft
w = 62,5 ft
Step-by-step explanation:
Perimeter of the rectangular fencing P = 250 feet
And sides of the rectangle a and w (width of rectangle)
Then
A = a*w
2a + 2w = 250 ⇒ a = (250 -2w)/ 2 ⇒ a = 125 - w
f(w) = (125 - w ) *w f(w) = 125w - w²
Taking derivatives both sides of the equation
f´(w) = 125 - 2w f´(w) = 0 125 - 2w = 0
w = 125/2
w = 62,5 ft ⇒ a = 125 - 62,5
a = 62,5 ft
f(max) = ( 62,5)²
f(max) = 3906,25 ft²
