The figure below is formed by 8 identical rectangles and 1 triangle. Find the
1 answer:
Answer:
Step-by-step explanation:
Base of triangle = length of the rectangle
Since, all are identical rectangles,
Length of a rectangle= 36/2 = 18 cm
Base of triangle = 18 cm
Height of triangle = length of the rectangle + width of the rectangle
Width of 6 rectangles = 36
Width of 1 rectangle = 36/ 6 = 6 cm
Height of the triangle = 18 + 6 = 24 cm
Area of the shaded triangle =
=
= 9 * 24
= 216 cm²

Step-by-step explanation:
Curtis is playing a trivia game.
Number of points earned for each correct answer = 2
Number of points lost for each correct answer = 0.25
Given that:
Number of correct answers given by Curtis = 21
Number of wrong answers given by Curtis = 4
To find:
Total score of the game by Curtis?
Solution:
First of all, let us find the points earned by correct answers.
Points earned by correct answers = Number of correct answers multiplied by Points earned on one correct answer.
Points earned by correct answers = 21 2 = 42
Now, let us find the points to be lost by wrong answers.
Points lost by wrong answers = Number of wrong answers multiplied by Points lost on one correct answer.
Points lost by wrong answers = 4 0.25 = 1
The score of the game can be calculated by subtracting the points lost from the points earned.
Score = 42 - 1 = <em>41</em>
