Lecture General mathematics: Lecture 23 - Ms. Fehmida Haroon

In this concept, you will learn to find the optimal value of a function that is associated with an optimization problem. At this point, you know how to analyze a function to find its minima and maxima using the first and second derivatives. This is a big deal! Finding the solution to some real-world problem (such as in finance, science, and engineering) often involves a process of finding the maximum or minimum of a function within an acceptable region of values. | General Mathematics ADE 101 Unit 3 LECTURE No. 23 PERIMETER Today’s Objectives Knowledge Test Length Definition: The measure of the distance across an figure. 4 Perimeter The distance around the outside of a rectangle. 6 Perimeter Definition: The sum of the length of all the sides of a polygon. Perimeter is the distance around the outside edge of a flat object. Perimeter is reported as a total number of linear units. Perimeter The distance around the outside of a shape is called the perimeter. 8 cm 6 cm 8 cm 6 cm The perimeter of the shape is 8 + 6 + 8 + 6 = 28cm. First we need to find he length of each side by counting the squares. The distance around the outside of a rectangle. length length width width Perimeter = (2 x L) + (2 x W) Perimeter 11 Try to find the perimeter of these rectangles. 1 2 2 3 3 4 5 6 Perimeter of a Rectangle To calculate the perimeter of an object or space, you will need to add the length and width, then multiply by 2. ( 2 + 4 ) x 2 = It means the same as: (2 + 4) + (2 + 4) = __ 2 4 Perimeter of a Square To find the perimeter of a square, multiply the side by 4. 3 x 4 = 3 Find the perimeter of these squares. 5 12 25 8 16 What is the perimeter of each of these shapes? 18cm 18cm 18cm 22cm 26cm Perimeter Measure each side of the triangle then add them together. 17 Perimeter of a Triangle To calculate the perimeter of a triangle you will need to add the sides. 3 + 4 + 5 = 3 4 5 Find the perimeter of these triangles. 5 5 5 3 4 5 3 3 3 6 8 10 Now find the perimeter of these shapes. They are not drawn to scale. 3cm 3cm 3cm 3cm 3cm 3cm 5cm 7cm 7cm 3cm 4cm 4cm 4cm 4cm 3cm 3cm 3cm 3cm Perimeter = 18cm Perimeter = 22cm Perimeter = 28cm Find the perimeter of each of these shapes? 9cm 5cm 5cm 2cm 4cm 5cm 4cm 2cm 11cm 7cm 4cm 3cm 3cm 3cm 7cm 6cm 6cm 11cm 2cm 4cm 5cm 4cm 9cm 5cm 5cm 2cm 4cm 5cm 4cm 2cm Perimeter = 36 cm 6cm 6cm 11cm 2cm 4cm 5cm Perimeter = 34 cm 11cm 7cm 4cm 3cm 3cm 3cm 7cm Perimeter = 42 cm 4cm 11cm 7cm 4cm 3cm | General Mathematics ADE 101 Unit 3 LECTURE No. 23 PERIMETER Today’s Objectives Knowledge Test Length Definition: The measure of the distance across an figure. 4 Perimeter The distance around the outside of a rectangle. 6 Perimeter Definition: The sum of the length of all the sides of a polygon.
