Β 20 +2β10 β 26.3 units
Step-by-step explanation:
Length AB is given as 10 units. Length AC is given as 2β10 β 6.325 units. The length BC is the difference of the x-coordinates of its end points, since they are on a horizontal line: 5 -(-5) = 10 units.
The perimeter is the sum of the lengths of the sides of the triangle.
Β P Β = AB +AC +BC = 10 +2β10 +10 = 20 +2β10 β 26.3 . . . units
