Answer:

AB = 7√2

Step-by-step explanation:

if a(x1,y1) and b(x2,y2) then

$ab = \sqrt{ {(x1 - x2)}^{2} +{(y1 - y2)}^{2}}$

Based on your points and on the formula above AB is:

$\sqrt{ {(3 - ( - 4))}^{2} + {(7 - 0)}^{2} } \\ \sqrt{ {(3 + 4)}^{2} + {7}^{2} } \\ \sqrt{ {7}^{2} + {7}^{2} } \\ \sqrt{2 \times {7}^{2} } \\ 7 \sqrt{2}$

The number which is express in each of the models as given in the image attached to the task content are as follows;

a). 1.37

b). 1.37

c). 1.37.

<h3>What numbers are expressed according to the given models in the task content?</h3>

It follows from the task content that the models describe that One flat represents 1 whole, One rod represents 1 tenth and one unit represents 1 hundredth.

It therefore follows from the task content that in each of the models, the algebraic sum of flat(s), rods and units as the case may be results in the value; 1.37 as the utmost number represented by the models.
