The area of a triangle is 24 square meters. If the base is 8 meters, what is the height? A. 4 meters B. 5 meters C. 6 meters D. 7 meters 相关知识点: 试题来源: 解析 C。解析:三角形面积等于底乘以高除以 2,已知面积是 24 平方米,底是 8 米,设高为 h,可列出方程 8h÷2 = 24...
The area of a triangle is 24 square meters. If the base is 8 meters, what is the height? A. 3 meters B. 6 meters C. 8 meters D. 12 meters 相关知识点: 试题来源: 解析 B。三角形面积 = 底×高÷2,所以高 = 面积×2÷底 = 24×2÷8 = 6 米。
