A = s2 (Area of a square is its side squared)
P = 4s (perimeter of a square is a side times 4)
A = 324 (the area of this square is 324 ft2)
fencing = $7 per foot
Let's find the side through the area. Find the root:
√324 = √s2
18 = s
Now the perimeter:
P = 4 * 18 = 72
Now to find how much the fencing will cost:
72 * 7 = 504
Answer:
you could stand at 5.0 ft and still be completely in the shadow of the tree
Step-by-step explanation:
From the diagram attached below;
We consider;
to be the height of the tree and 
to be the height of how tall you could be and still be completely in the shadow of the tree.
∠D = ∠B = 90°
Also;
ΔEAD = ΔBAC (similar triangles)
Therefore, their sides will also be proportional
i.e
By cross multiply
225x = 45 × 25
x = 5.0 ft
Therefore, you could stand at 5.0 ft and still be completely in the shadow of the tree
That is, log x = k if and only if 10 k = x.
Y – y1 = m(x – x1)
y-(-1)=-5(x-2)
Y+1=-5(x-2)
