Question

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

Answer 1

D = 9.85 units long

Explanation:

Answer 2

D = 9.85 units

Explanation:

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

Using Distance Formula to find the length

=> Distance Formula =
`√((x2-x1)^2+(y2-y1)^2)`

=> D =
`√((10-1)^2+(3-7)^2)`

=> D =
`√((9)^2+(-4)^2)`

=> D =
`√(81+16)`

=> D =
`√(97)`

=> D = 9.85 units (Upto 3 sfs)
