y= 2*3-4x;
differentiate with respect to t we get dy = -4xdt; -- eqn 1
given dt = 4 substitute in eqn 1 we get , dy =-4 x( 4) = -16x; --eqn2
given x=1 then sub then the value of x in eqn 2 we get dy = -16(1)=-16
ie Ans dy = -16

No, it is wrong.

A = 2(wl+hl+hw)

A = 2(11x5.6+11x7.2+5.6x7.2)

A= 362.24
