To compute the area of an isosceles triangle, use the formula: Area = (base * height) / 2Where,The base is the length of the base of the isosceles triangle. The height is the perpendicular distance from the base to the opposite vertex....
The height of a triangle is 8 cm and the base is 6 cm. What is the area of the triangle? A. 14 square cm B. 24 square cm C. 48 square cm D. 12 square cm 相关知识点: 试题来源: 解析 B。这道题考查三角形面积计算。三角形面积 = 1/2×底×高,即 1/2×6×8 = 24 平方厘米...
解析:The triangle is a 30°-60°-90° triangle, so the ratio of the lengths of the legs is 1 to. Since the length of the shorter leg, AB, is 6, it follows that the length of the longer leg, AC, is 6. The area of the triangle is therefore, or 18. The correct answer is...
