Review perimeter and area Quiz
Objectives (checks) Understand, select and use units of appropriate size and type to measure angles, lengths/distances, area, surface area and volume. Solve contextual problems that require calculating the area of triangles and parallelograms. Prepares for: 0506.4.2 Decompose irregular shapes to find perimeter and area.
Remember!!! Perimeter - all sides added together Area of square and rectangles - A = length x width - A = l x w
Remember!!! Area of parallelograms - A = base x height - A = b x h Area of triangles - A = ½ x b x h
