The length of the altitude PM is 11 cm.
Explanation:
Given : ΔABC ≈ Δ PQR
ar (ABC) = 81 cm²
ar (PQR) = 121 cm²
Length of altitude AD = 9 cm
To find : altitude PM
If two triangles are similar then the ratio of the area of the triangles is equal to the ratio of the square of the corresponding altitudes.
Hence, the length of the altitude PM is 11 cm.
