Please find the area of the figure!!
Murrr4er [49]

The figure consists of a rectangle and a circle.

first lets find the sides of the triangle

sides of the triangle are 4+4=8 and 3+1=4

therefore area of the rectangle is 8*4=32

now area of semicircle =πr^2/2 = π2^2/2=2π=6.3

we have to add the area of rectangle with the area of semicircle

this is because it the given figure no part of area of circle and rectangle are in common.

therefore total area of given figure = 32+6.3=38.3

43 5/12 x 11 Please help
zzz [600]
The perimeter is the sum of side lengths. Opposite sides of a rectangle are the same length, so the perimeter is
  P = 11 +43 5/12 +11 +43 5/12
    = 2(11 +43 5/12)
    = 2(54 5/12)
  P = 108 5/6 . . . . feet

The area is the product of length and width. It doesn't matter which of the given dimensions you consider length or width, since you multiply them either way.
  A = 11 * 43 5/12
    = 473 +55/12
  A = 477 7/12 . . . . square feet
