The area of the track will be 78501 m². The area of the track is equal to the area of the circle.
<h3>What is the area?</h3>The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square meters and other similar units are used to measure area.
The area of the track is found as;
Hence, the area of the track will be 78501 m².

Since the scaling factor of the dilation (0.5) is fewer than 1, it shrinks (make smaller) the triangle around the origin (zero). Intuitively, the dilation is getting the points of the triangle closer to zero (in a way that preserves the shape of the triangle).
Formally, to know the coordinates of a point of the triangle after the dilation, we just need to multiply the original coordinates of the point by the scaling factor (this works for the dilation is around zero).
The original coordinates of D are
Multiplying them by the scale factor, we get
The coordinates of D after the given dilation is
