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

omeli [17]

Answer:

1 * 10^12

Step-by-step explanation:

Scientific notation is a representation of a large number in a short form. The answer, 1*10^12 (read as ten to the twelfth power) essentially says that the number when expanded is 1 with 12 zeros appended to it. If you did a number like 7 trillion you would have 7 * 10^12.

Same thing can be applied for 1,000,000 (one million).

1 * 10^6 because one million has 6 zeros appended to it.
