1 pace = 0.9 m
37 paces = x
Cross multiply to get:
x=37*0.9/1=?
When you cross multiply, multiply the complete diagonal (the one occupied by two numbers, i.e. 0.9 and 37) and divide by the number diagonally across from x, i.e. 1.
Similarly,
1 pace = 0.9 m
y paces = 122 m.
Cross multiply to get the answer.

a.)PF= D/ Ave no. of paces
D = PF x Ave no. of Paces
0.09 x 37
=33.3 m
b.) PF= D// Ave no of pace
122 m/ 0.9
=135.556 paces
D = PF x Ave no. of Paces
0.09 x 37
=33.3 m
b.) PF= D// Ave no of pace
122 m/ 0.9
=135.556 paces
