GMAT data sufficiencyIs the perimeter of triangle abc greater than 20?A.bc-ac=10B.the area of triangle abc is 20
GMAT data sufficiency
Is the perimeter of triangle abc greater than 20?
A.bc-ac=10
B.the area of triangle abc is 20
GMAT data sufficiencyIs the perimeter of triangle abc greater than 20?A.bc-ac=10B.the area of triangle abc is 20
单独A或者B都可以得出这个结论.
首先我们来看A, BC-AC=10,根据第三边大于其余两边之差,得出AB>10 而BC又大于10,所以周长必定大于20.
B,最迅速的方法是代数法,我们知道面积一定的情况下,等边三角形具有最小的周长.
等边三角形并且面积是20的情况下,a=6.8,周长加起来也大于20.
因此单独A或者B都可以.
