Nine groups of 8 students and one group of 6 students. 9 x 8 = 72. 78 - 72 = 6.
CAB=17 degrees
CAB is the first section to the left. Point A is the center of your measurer, and the C and B are the end points of the angle. To find out the measure of angle CAB, you count the marks made in black between C and B, which results in 17 degrees—three less than the long mark at 20.
Length = 7width - 2
perimeter = 2 width + 2 length
96 = 2 width + 2 (7width -2)
96 = 2 width + 14 width - 4
100 = 16 width
then width = 6.25 cm and length = 7(6.25) - 2 = 41.75 cm
