Question

Use the distance formula to find the perimeter

of the triangle with vertices at the points
(-1,0), (2, 0), and (2, 7). Round to two decimal
places if necessary.

Answer 1

See below.

Explanation:

`(-1,0) \text{ vs} ( 2,0)`

`√( ( (-1-2)^2 + (0-0)^2) )= √(( (-3)^2 + 0^2) )=√(( 9+0))= √((9) = 3)`

`(-1,0) \text{vs} ( 2,7)`

`√(( (-1-2)^2 + (7-0)^2) )= √(( (-3)^2 + (7)^2) )=√(( 9+49)) =√((58))`

(2,0) vs (2,7) has distance of 7

Answer is
`10+√(58)` (17.6157731058639082856614110271583)
