Q. 24

# In triangles BMP

Given: PB = 5 cm,

MP = 6 cm,

BM = 9 cm and,

NR = 9 cm

Now, it is also given that: ΔBMP ~ ΔCNR

When two triangles are similar, then the ratios of the lengths of their corresponding sides are proportional.

…(i)

CN = 54/6 = 13.5 cm.

Similarly,

CR = 7.5 cm

Perimeter of ΔCNR = CN + NR+ CR = 13.5+9+7.5=30 cm
