I need help, I did the plotting already but I'm confused-

quadrilateral, 3

Step-by-step explanation:

I think you put the grocery store at the wrong location.  You graphed point (-1, 1) while it should be at (1, -1) (i.e. one to the right then one down)

The figure drawn by 4 points on a plane (assuming no 3 points lie on the same line) is a quadrilateral

The school is at (-2, -1) while the grocery store is at (1, -1).  A straight line connecting them is a horizontal line of length 3, so the two points are 3 apart.

It is possible to find the distance between the points you actually drew, but I suspect that is a bit in the future for you.

Quadrilateral/Right Trapezoid, 3

Step-by-step explanation:

`1234567890-=/*-qwertyuiop[]asdfghjkl; '\\zxcvbnm,./+ /

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
