2. Perimeter and Area

3. Who can recall formulas of perimeter and area.
M. 4c Develop, compare, and use formulas to estimate and calculate the perimeter and area of rectangles, triangles, and parallelograms. (DOK 2)
Who can recall formulas of perimeter and area.
On perimeter you will add all the sides of the polygon or you can use the formulas: square 4s; rectangle 2l+2w or 2(l+w).
On area the square is A=side squared; rectangle A=l x w; triangle ½ b x h; parallelogram b x h.
