问几道英语奥数题1.We know the area of A is four times of B.If the area of B is 6平方厘米 and the perimeter of B is 16cm.the perimeter of A is _____.2.There is a triangle,and it is an isosceles triangle (等腰三角形).We know a and b ar
1.请问这道题有图吗?(不能确定A和B的形状)
2.∵h的平方+(c/2)的平方=b的平方
∴h的平方=5的平方-(8/2)的平方
∴h=3
∴三角形的面积为8×3÷2=12(平方厘米)
