What is the perimeter of the figure shown above? a. 10 cm c. 15 cm b. 20 cm d. 19 cm

c,15

Step-by-step explanation:

There are 4 sides to this figure (trapezoid). The left slanted side and the right most vertical side, combined with the top and bottom horizontal sides, will get us the perimeter.

left slanted side = 5 yards

right most vertical side = 4 yards (see note below)

bottom side = 9 yards

top side = 6 yards

Add up the four sides mentioned: 5+4+9+6 = 9+15 = 24

note: the rectangle has opposite sides that are the same length. While the right most side isn't labeled, it is the same length as the left side of the rectangle, so both are 4 yards long.

Another thing I should probably mention is that we do not add in the interior 4 yard side. The perimeter is only the outer or exterior sides we care about. Think of it like we're trying to fence around some property lot and we don't want to subdivide the property up. Finding the perimeter will help us find the amount of fencing needed to surround the property.

B. 24 in

Step-by-step explanation:

Add the known sides = 19 in

To solve for the two unknown sides -

Side across from the vertical 3 in is the same, so add another 3 inches to 19 = 22 in

For the side across from the 7in you need to subtract the horizontal sides next to it that you already know.

7 = 3 + 2 +x

x = 2

so add 2 in

22 + 2 = 24in

b. 64 cm

Step-by-step explanation:

Perimeter of the figure

= 12 + 2(16) + 2(10)

= 12 + 32 + 20

= 64

c

Step-by-step explanation: cause it is

D

Explanation:

add all the know sides 8+8+3+5=24

perimeter of half a semicircle=circumference of half a semicircle

if circle is C=π×d

than semi C=1/2×d×π

C=½×4×π

C=2pi

so 24+2pi

Option B is correct.

Step-by-step explanation:

Figure is attached with marking of vertices.

from figure ∠A and ∠D are right angle

So, we can break the given figure in to a triangle BEC & a Rectangle ABCD

We know that opposite side of the rectangle are equal. So,

CD = AB = 16 cm

So the Perimeter of the given figure = AB + BE + EC + CD + AD = 16 + 10 + 10 + 6 + 12 = 64 cm

Therefore, Option B is correct.
