2.24 is 4% 56. Convert the 4% to 0.04 and multiply the 56 by the 0.04.

**Answer:**

42.9m

**Step-by-step explanation:**

The topic is on similar triangle

you are comparing triangle MNP with triangle MAB

side AB is similar to NP

side MA is similar to MN

side MB is similar to MP

now MA = MN - AN

= 67.2 - 32

= 35.2m

MA/MN = MB/MP

35.2/67.2 = x/81.9

cross multiply and solve

x = 42.9m

Complete question is attached.

------------------------------------------

Consonants (A) = 56

Vowels (B) = 42

Blank = 2

------------------------------------------

Total letters = 100

Two letters are drawn with replacement.

P(A) = 56/100 = 0.56

P(B) = 42/ (100-1) = 0.424

P(A).P(B) = 0.56*0.424 = 0.2376

Centre = (-13,-1)

Radius = 9
