Given:Length = 4,450.5 metersWidth = 2,890 meters 1 kilometer = 1,000 meters Length: 4,450.5 meters * 1km/1,000 meters = 4,450.5 km/1,000 = 4.4505km Width: 2,890 meters * 1km/1,000 meters = 2,890 km/1,000 = 2.89 km 4.4505 km - 2.89 km = 1.5605 km The length of the fence is 1.5605 km longer than the width of the fence.
As shown in the image, we have a 30 degree angle and x, which is what we want. By doing tan30, we can find x, so tan30=x/70 and 70*tan30=x= 70*sqrt(3)/3. 120-x=height of first tower = 120-(70*sqrt(3)/3) = roughly 79.59
