m=p-2b/2
p=57.4
b=8.7

Given the value of p and b in the equation (( p-2b ) / 2 ), the value of m is 20.
Given that;
First, we substitute the value of p and b into the equation.
m = ( p-2b ) / 2
m = ( 57.4 - 2(8.7) ) / 2
m = ( 57.4 - 17.4 ) / 2
m = 40 / 2
m = 20
Given the value of p and b in the equation (( p-2b ) / 2 ), the value of m is 20.
