Question 863775
For perimeter, add the lengths together, starting at the bottom right and moving clockwise.
{{{P=4x+4+3x+6+4x+4+x+2x+2+3+2+x+2+3+2x+2}}}
{{{P=17x+28}}}
For the area, think of the letter as 5 rectangles stacked on top of each other. 
The area of a rectangle is {{{A[r]=L*W}}}
Some of the widths you have to calculate using subtraction.
Starting at the bottom again,
{{{A=(4x+4)x+(4x+4-(2x+2))(3)+(4x+4-(2x+2)+2)x+(4x+4-(2x+2))(3)+(4x+4)x}}}
{{{A=(4x+4)x+(4x+4-2x-2)(3)+(4x+4-2x-2+2)x+(4x+4-2x-2)(3)+(4x+4)x}}}
{{{A=(4x+4)x+(2x+2)(3)+(2x+4)x+(2x+2)(3)+(4x+4)x}}}
{{{A=2(4x+4)x+2(2x+2)(3)+(2x+4)x}}}
{{{A=(8x^2+8x)+(12x+12)+(2x^2+4x)}}}
{{{A=10x^2+24x+12}}}
