Answer 10

You have 5 sides that are rectangles and 2 bases that are pentagons

the total perimeter of the pent is 20

Answer 11

okay

Answer 12

Ahh! Perimeter.

Answer 13

k is the height of a basic triangle that makes up the pentagon, and s is a side of the pentagon:

ks/2 is the area of 1 triangle, and there are 5 triangles: 5ks/2 for the entire pent

there are 2 pents to account for; 2*5ks/2 = 5ks

there are 5 rectangles of area: 6*s

Answer 14

so, what does that give us?

Answer 15

A=30 r 36?

Answer 16

Find the total area, in terms of K

there is no K in 30 or 36

Answer 17

oh

Answer 18

Surface Area = 5ks + 5(6s)

you should be able to determine s ..... and k is the unknown, just simplify to your hearts content

Answer 19

lol okay thank you that was very helpful. medal for you!
