Unit 8 Polygons — And Quadrilaterals Homework 2

Find the perimeter of a rectangle with a length of 6 cm and a width of 4 cm.

Find the sum of the interior angles of a pentagon.

The perimeter of a rectangle can be found using the formula: P = 2 l + 2 w , where l is the length and w is the width. Substituting the values given, we get: P = 2 ( 6 ) + 2 ( 4 ) = 12 + 8 = 20 cm. Conclusion Unit 8 Polygons And Quadrilaterals Homework 2 is an important assignment that tests students’ understanding of the properties and characteristics of polygons and quadrilaterals. By reviewing the key concepts, practicing problem-solving, and using diagrams and illustrations, students can successfully complete the assignment and build a strong foundation in geometry.

The sum of the interior angles of a polygon can be found using the formula: ( n − 2 ) × 18 0 ∘ , where n is the number of sides. For a pentagon, n = 5, so the sum of the interior angles is: ( 5 − 2 ) × 18 0 ∘ = 3 × 18 0 ∘ = 54 0 ∘ .
