Area & Perimeter

Finding the area of polygons by composing and decomposing into other shapes. Calculating the area & perimeter of circles and composite shapes. Solving real-world problems based on area & perimeter.

Mapped to CCSS Section# 6.G.A.1, 7.G.B.4, 7.G.B.6

Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems. Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area a circle. Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
