Answer:

3rd option - 14 m²

Step-by-step explanation:

First we know that the square's area will be 2×2 = 4

To calculate the area of a triangle we know the vertical height is 2.5 and the base length is 2 so we can use the formula b×h/2 to give the area of one triangle:

2.5×2 = 5

5÷2 = 2.5

So the area of 1 triangle is 2.5 m²

Since there are 4 triangles we multiply the area of 1 traingle by 4:

2.5×4 = 10

We add the area of the 4 triangles to the area of the square to give our final answer of :

10 + 4 = 14

14 m²

Find a rational number halfway in between the two numbers. three sevenths and one tenth
strojnjashka [21]
Answer:
The rational number is : 37/140

Explanation:
The first number given is three sevenths which can be written as 3/7
The second number given is one tenth which can be written as 1/10

Now, we want to get the midpoint between these two numbers. The midpoint can be calculated as follows:
midpoint = (first number + second number) / 2
midpoint = [(3/7) + (1/10)] / 2 
midpoint = 37/140

Hope this helps :)

Step-by-step explanation:

Most construction starts with a diagram.

_____

<em>Additional comment</em>

You may actually start by finding a pattern you like, then figuring the material required to construct the pattern, then working backward to determine the dimensions you need to use to stay within your material budget. You will probably draw a diagram at many points in the planning process.
