Question

Work out the length of ab, give your answer to 3 significant figures

Answer 1

Answer:

D = 9.85 units

Step-by-step explanation:

A (1,7) and B(10,3)

Using Distance Formula to find the length

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

=> D = $\sqrt{(10-1)^2+(3-7)^2}$

=> D = $\sqrt{(9)^2+(-4)^2}$

=> D = $\sqrt{81+16}$

=> D = $\sqrt{97}$

=> D = 9.85 units (Upto 3 sfs)
