Equilateral triangle terms of side length "a" can be derived directly using the Pythagorean theorem or using trigonometry. The area of a triangle is half of one side "a" times the height "h" from that side: The legs of either right triangle formed by an altitude of the equilateral triangle are half of the base "a", and the hypotenuse is the side "a" of the equilateral triangle. The height of an equilateral triangle can be found using the Pythagorean theorem so that Substituting "h" into the area formula (1/2)"ah" gives the area formula for the equilateral triangle: Using trigonometry, the area of
Borough of Wokingham closest higher education provider is the main Whiteknights Park campus of the University of Reading immediately north-west. Elevations range between 30 and 70 metres above sea level except higher in about 5% of the borough. The highest is an escarpment containing parts of the rural and wooded northern area, the hinterland of three Thames-side villages, facing the 30-mile long Chilterns AONB, west and north. A geological part of that range of hills, Bowsey Hill reaches 137m, in Wargrave civil parish, from the river. Approximately a right-angled triangle, the borough is long north to south. It uses as its longest edge
