the perimeter of the figure is:

10 + 4 + 4 + (10/2 * pi) / 2 = 18 + 5/2 pi

to the nearest hundredth (assuming pi is 3.14), that would be 18 + 7.85 = 25.85.

now for the area:

10 * 4 + (10/2)^2 * pi = 40 + 25pi

to the nearest hundredth, that would be 40 + 78.5 = 118.5.

hope this helped! sorry if my explanations weren't too clear. please let me know if you are confused about anything i did

Here's what I get for the perimeter.

4                          one short side of partial rectangle

4                          other short side of partial rectangle

10                          long side of partial rectangle

10π                                     The circumference of a circle is π times its diameter, i.e., π • 10 in this figure.

——   =  15.70                     Using 3.14 for the value of π, the circumference of the entire circle would be 31.4

2                                        But there's only half a circle, so we take half of 31.4

33.70 inches        Total up the above.

The first answerer got the area correct.

oh, oops, i forgot that the circumference is just the diameter * pi.

good work, Guest !!
