We know that

[perimeter of a rectangle]=2*[width+height]
width=44 1/4 in-----> (44*4+1)/4----> 177/4 in
height=25 in
so
[perimeter of a rectangle]=2*[25+177/4]-----> 2*[(4*25+177)/4]
=2*[277/4]-----> 277/2-----> 138.5 in-----> 138 1/2 in

the answer is
138.5 in or 138 1/2 in

In a particular region there is a uniform current density of 18 a/m2 in the positive z direction. what is the value of line inte
Ugo [173]
By Stokes' theorem, the integral is 0. If R is the triangular region bounded by the given line segments composing the curve C, then

\displaystyle\int_{\partial R}\mathbf b\cdot\mathrm d\mathbf s=\iint_R\nabla\times\mathrm d\mathbf r

where \nabla\times F=\mathrm{curl}(0,0,18)=0.

Just to verify this, we can parameterize the path by

C=C_1\cup C_2\cup C_3
\begin{cases}C_1:=\{(4d,3dt,0)~|~0\le t\le1\}\\C_2:=\{(4d(1-t),3d(1-t),0)~|~0\le t\le1\}\\C_3:=\{(4dt,0,0)~|~0\le t\le1\}\end{cases}

\displaystyle\int_C\mathbf b\cdot\mathrm d\mathbf s
=\displaystyle\int_0^1(0,0,18)\cdot(0,3d,0)\,\mathrm dt+\int_0^1(0,0,18)\cdot(-4d,-3d,0)\,\mathrm dt+\int_0^1(0,0,18)\cdot(4d,0,0)\,\mathrm dt
=0+0+0=0
