Circle
The distance around the circle is a circumference. The distance across the circle is the diameter (d). The radius (r) is the distance from the center to a point on the circle. (Pi = 3.14) More about

Rectangle:
Area = Length X Width
A = lw
Perimeter = 2 X Lengths + 2 X Widths
P = 2l + 2w
Yes, the area of a circle can be represented in a rectangular form using the formula for the area of a circle, (A = \pi r^2). If you imagine unrolling the circle into a rectangle, you can think of it as approximating the circle with a series of infinitesimally thin rectangles, where the height of each rectangle corresponds to the radius and the width corresponds to a segment of the circle's circumference. While the circle and rectangle are geometrically different, the area can be calculated and compared using similar mathematical principles.
Area = length x width you may try the online calculator linked below that is related to this area and perimeter calculation of common shapes like rectangle, circle, triangle, parallelogram, rhombus and trapezoid.
Area of circle = pi*212 = 1385.44236 square cm Area of rectangle = 1385.44236 square cm Lenght of rectangle = 1385.44236/18 = 76.96902 cm Perimeter of rectangle = 2(76.96902)+2(18) = 189.93804 cm

Calculate the area of a rectangle and of the semicircle separately, then add.
It depends on what you are trying to find the area of. The area of a rectangle is calculated by multiplying the length of the rectangle times the width of the rectangle. The area of a circle is calculated by multiplying pi times the radius of the circle squared. See the Related Links for more information on calculating area.
area of a circle = area of a rectangle(parallelogram) formed by the sectors of circle with pi as length and radius as bradth.
