Eight coins fit exactly on a rectangular sheet of paper when lined up in 4 columns and two rows. each coin is in the shape of a regular dodecagon, a polygon containing 12 sides. what fraction of the paper sheet will not be covered?

≅0.034

Step-by-step explanation:

The graph shows a rectangle and 8 dodecahedrons but a dodecahedron inscribed in a square is seen, so it is enough to calculate the fractions of areas between the square and the dodecahedron

Square area

Area of a right triangle  

Area fraction

≅0.034

Note: The fractions of the sides of the square and the right triangle are determined by assigning values to L

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
