Grade: 8-a Lesson: S3-L3 |
Explanation: Hello Students, time to learn examples. Let us take turns and read each example. Explain each step. Pay special attention to steps and pictures and communicate in your own words. |
Examples:
Find the perimeter of an triangle. The length of two sides of the triangle (a) is 30 cm, and the base is 8 cm.
Step 1a
|
|
Given, length(a) = 30 cm base(b) = 8 cm |
|
Explanation: The length is 30cm, and the base measures 8cm. |
|
Step 2a
|
|
Perimeter of triangle (P) = 2a + b |
|
Explanation: The formula for finding the perimeter of an triangle is P = 2a + b. |
|
Step 3a
|
|
Therefore, the perimeter of the triangle is 68cm. |
|
Explanation: To find the value of P, we substitute 30 for the variable and solve the equation 2(30) + 8, which results in P being equal to 68 cm. |
