Check the picture below.
you can pretty much just count the units off the grid.
the perimeter is the length of all sides summed up.
F(6) = 2(6) + 1
= 12 +1
= 13
f(3) = 2(3) + 1
= 6 + 1
= 7
f(-5) = 2(-5) + 1
= -10 + 1
= -9
20 x 3/4 =
20/1 x 3/4= turn the 20 into a fraction
20 x 3 / 1 x 4
60/4 =
15
The answer is 15. :)
3 1/4 * 2 3/4 = 13/4 * 11/4 =143 /16 = 8 15/16 inches
