Answer:

Formular for coordinate length:

length =  \sqrt{ {(x_{1}  - x _{2} )}^{2}  +  {(y_{1}  - y_{2})}^{2} }

In considerance of coordinates given of A and B

x _{1} \: \:  is \:  \: 2 \\ x_{2} \:  \: is \:  \:  - 2 \\ y_{1}  \: \: is \:  \: 3 \\ y_{2} \:  \: is \: \:  0

therefore substitute:

length =  \sqrt{ { \{2 - ( - 2) \}}^{2}  +  {(3 - 0)}^{2} }  \\  \\  =  \sqrt{ {(2 + 2)}^{2} +  {3}^{2}  }  \\  =  \sqrt{ {4}^{2} +  {3}^{2}  }  \\  =  \sqrt{16 + 9}  \\  =  \sqrt{25}  \\  \\ { \boxed{ \boxed{length  \:  \: is \:  \: 5 \: units}}}
