Answer 3

What @welshfella was saying.
So first multiply 27 x 26, what is your answer?

Answer 4

the area of each triangle = 1/2 * base * height
= 1/2 * 26 * 27

Answer 5

after you have worked that out the area of the heptagon = 7 times that.

Answer 6

lagging

Answer 7

the apotherm 27 is also the height of each triangle

Answer 8

the vertex of each triangle is also the center of the regular heptagon ( 7 - sides)

Answer 9

702

Answer 10

understand?

Answer 11

yes

Answer 12

1/2 * 26 * 27 * 7

Answer 13

its not 702

Answer 14

i think yiuve worked out 1/2 * 26*27 * 2

- there are 7 triangles altogether
