Answer 12

im not done explaining

Answer 13

ok

Answer 14

so the bottom and side of the rectangle are still the same size as the sides of the square and since there are 3 squares in each row, all we have to do is retriceup the 12.4 3 times for width and once for height

Answer 15

and for the trappizoide, we know that the shorter side takes up 1 square and the longer side is three, so the shorter side is 12.4 and the longer side is 37.2 like the width of the rectangle

Answer 16

and the height is the same 12.4 as well in the trapizoide

Answer 17

for area of the rectangle just do 37.2x12.4
