If the ratio of altitudes of two similar triangles is 1: 2, then the ratio of their areas is -
1 : 1
1 : 4
4 : 1
1 : 2
Insufficient data
Area of a triangle = 12×base×height So data is insufficient.
Which among the following is/are correct?(I) If the altitudes of two similar triangles are in the ratio 2:1, then the ratio of their areas is 4:1.(II) PQ∥BC and AP:PB=1:2. Then, A(△APQ)A(△ABC)=14
