The answer is c I am positive
Answer:
6/52 is a reasonable answer
Answer:
43.8
Step-by-step explanation:
Remark
Are there ever a lot of assumptions!!
- The rectangles are all the same size
- the triangles are the same size
- The rectangles are indeed rectangles.
- The triangles are isosceles.
- The two equal sides are both equal to the width of the rectangles.
Area of the rectangles
A = L * W
L = 4 m
W = 3 m
Area = 4*3 = 12
There are 3 rectangles so the total area = 3*12 = 36
Area triangles
Area = 1/2 b * h
b = 3
h = 2.6
Area = 1/2 * 2.6 * 3
Area = 1/2 7.8
But there are 2 of them so the area for the 2 is
Area = 2* 1/2 7.8
Area = 7.8
Total area = 36 + 7.8
Total area = 43.8
Answer: 20x+3
Explanation:
We find the area of a triangle by multiplying and then dividing by 2. In this problem, I decided to split the triangle in half. So now. We have two equations to find area.
3x(2x)(5)
2x(x+6)(5)
Multiplying the first problem, we get 30x. With the second problem, we get 10x+6. Adding these areas, we get 40x+6. Though, we have to divide by two because it is a triangle. That is how I got my answer of 20x+3
