Answer:
0.015 m²
Step-by-step explanation:
Since we need the area in square meters, we need to first convert our centimeter values into meters.
![\frac{1m}{100cm} =10cm](https://tex.z-dn.net/?f=%5Cfrac%7B1m%7D%7B100cm%7D%20%3D10cm)
1 · 10 = 10
10/100 = 0.1 m
![\frac{1m}{100cm} =15cm](https://tex.z-dn.net/?f=%5Cfrac%7B1m%7D%7B100cm%7D%20%3D15cm)
1 · 15 = 15
15/100 = 0.15 m
The area of a rectangle is a = l · w. Plugging in the given values, we get:
a = 0.1 × 0.15
a = 0.015 m²

Answer:
(c)
"The given statement is true, by definition of length of a vector
,
"
Step-by-step explanation:
(a) ![v \bullet v = || v ||^2](https://tex.z-dn.net/?f=v%20%20%5Cbullet%20v%20%3D%20%7C%7C%20v%20%7C%7C%5E2)
That is completely correct Remember that if
then
![v \bullet v = x_1*x_1+x_2*x_2+x_3*x_3 = x_1^2+x_2^2+x_3^2 = ||v||^2](https://tex.z-dn.net/?f=v%20%5Cbullet%20v%20%3D%20x_1%2Ax_1%2Bx_2%2Ax_2%2Bx_3%2Ax_3%20%3D%20x_1%5E2%2Bx_2%5E2%2Bx_3%5E2%20%3D%20%7C%7Cv%7C%7C%5E2)
Therefore the correct answer would be (c).
"The given statement is true, by definition of length of a vector
