For two similar triangular prisms:
A2 / A1 = l2² / l1² = ( l2 / l1 )²
In this case:
A2 / A1 = = 121 / 49 = 11² / 7 ² = (11 / 7 )²
The ratio of the corresponding side lengths is 11 / 7
the area of corresponding faces of two simalar triangle prisms are 49cm squared and 121 cm squared. what is the ratio of the corresponding side lengths?
