Answer:
24 units
Explanation:
the length of the 2 legs we can easily determine via the covered side lengths of the unit squares.
leg1 = 8 units
leg2 = 6 units
to get the length of the Hypotenuse, we need to use Pythagoras
c² = a² + b²
c being the Hypotenuse, a and b being the legs.
c² = 8² + 6² = 64 + 36 = 100
c = 10 units
therefore, the perimeter of the triangle is
10 + 8 + 6 = 24 units
