= 2(1/2*7*24)+(22*24)*(7*22)+(22*24)

= 2(84)+528+154+528

= 168+528+154+528

=1378m^2

B) V= πr^2h

= π*10^2*20

= π*100*20

Use substitution to solve the system of equations.

I believe you haven't included the system of equations for us to solve.

However, I will tell you that you need to solve for one variable in an equation and substitute that into the other equation.
For example:
x = yz; z = x/y
a = zb; a = (x/y)b

Hope this helps!
