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:
10.25
Step-by-step explanation:
Unit price means per 1
71.75/7 = 10.25 each
You want to spread them out evenly, so I would do 2 of the 16 group, and 1 white marble in each group, which makes 8 groups.
13. 72 + 72 + X = 180
X = 180 - 144
X = 36
angle A= 36
14. X + X + 101 = 180
X+X =180-101
X+X= 79 divided by 2
X= 39.5
angle B= 39.5
