Solution

The correct option is B $5^i + 4^j$
The length $A B$ and $A D$ can be written in the vector form as
$- - \to A B = 5^i + 0^j$ and $- - \to A D = 0^i + 4^j$
Thus, $- - \to A B + - - \to A D = (5^i + 0^j) + (0^i + 4^j) = 5^i + 4^j$

In a rectangle ABCD where A is origin as shown in the figure, what is −−→AB+−−→AD ?

The correct option is B 5^i+4^jThe length AB and AD can be written in the vector form as −−→AB=5^i+0^j and −−→AD=0^i+4^j Thus, −−→AB+−−→AD=(5^i+0^j)+(0^i+4^j)=5^i+4^j

In a rectangle $A B C D$ where $A$ is origin as shown in the figure, what is $- - \to A B + - - \to A D$ ?

The correct option is B $5^i + 4^j$
The length $A B$ and $A D$ can be written in the vector form as
$- - \to A B = 5^i + 0^j$ and $- - \to A D = 0^i + 4^j$
Thus, $- - \to A B + - - \to A D = (5^i + 0^j) + (0^i + 4^j) = 5^i + 4^j$
