Answer:
D = 12.94 m
Step-by-step explanation:
Coordinates of first tree = A(0,8)
Coordinates of second tree = A(12,4)
We need to find the distance between the two trees. We can find it using distance formula for coordinates as follows :
![D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
We have, x₁ = 0, x₂ = 12, y₁ = 8, y₂ = 4
Now using distance formula,
![D=\sqrt{(12-0)^2+(4-8)^2}\\\\=\sqrt{144+16} \\\\=12.64\ m](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%2812-0%29%5E2%2B%284-8%29%5E2%7D%5C%5C%5C%5C%3D%5Csqrt%7B144%2B16%7D%20%5C%5C%5C%5C%3D12.64%5C%20m)
So, the distance between the two trees is 12.64 m.
