6. Review What is PERIMETER? PERIMETER is the total distance around the shape How do you find PERIMETER? PERIMETER = add up the sides

7. Missing Sides Sometimes, you’re missing numbers on your shape You need to solve for the missing side(s) BEFORE finding the perimeter

8. Missing Sides Match the PARALLELS – Lines that do not cross each other – Same size on the same side or opposite side

9. Missing Sides ADD the shorter sides to find the LONGER side 3 4

10. Missing Sides Use the LONGER side to solve for the missing shorter side – ADD up the shorter sides; SUBTRACT from the longer side

11. Given Perimeter If given the perimeter, PLUG in the information you know SOLVE for the missing sides Perimeter = 30 10 Tools: Add Subtract Divide ?
