Answer:
Rectangle 1 area: 53 units squared
Shape 2 area: 43.75 units squared
Step-by-step explanation:
Shape 1:
We need to find the area of the two triangles in this rectangle and subtract it from the total area of the rectangle.
Total area of the rectangle:
13 * 5 = 65
Area of triangles (they are congruent):
1/2 * 4 * 3 = 6
6 * 2 = 12
65 - 12 = 53
The area of the shaded part is 53 (I don't know what your unit of measurement is. Just say units.)
Shape 2:
First, let's find the area of the parallelogram at the top.
10 * 3 = 30
Now, let's find the area of the rest of the shape. Triangle first...
1/2 * 4 * 1.5 = 3
Now, the rectangle and the tiny triangle we can section out at the end:
7 * 1.5 = 10.5 + 1/4 (Triangle) or 0.25 = 10.75
Total area: 10.75 + 3 + 30 = 43.75

Answer: 75%
Step-by-step explanation:
The test had 32 questions and from these 32 you were able to get 24 questions right.
The percentage of questions you got right is the percentage of 32 that 24 is.
= Number of correct questions / Total number of questions * 100%
= 24 / 32 * 100%
= 75%
Answer:
112 rooms
Step-by-step explanation:
Simply if 10% of 140 is 14 20% of 140 is 28. So then 28 substract 140 is 112
3x + 2y = 0
- 3x - 3x
2y = -3x
2 2
y = -1.5x
The gradient of the straight line of the function is -1.5.
