Answer: unit
Step-by-step explanation:
Since Here Δ ABC is a isosceles triangle.
Also, and
Thus, ∠ ADH = 90°
That is, Δ ADH is the right angle triangle.
In which, AD = a unit and HD = b unit
And, By the definition of Pythagoras theorem,
⇒
⇒
Since, the perimeter of a triangle = sum of the all sides of the triangle.
Therefore, perimeter of ΔADH = AD + DH + AH
= unit
D) a+2c=10.5
Since b=c+
a+b+c=10
a+(c+1/2)+c=10
a+2c+1/2=10
a+2c=9.5
Since b=c+
a+b+c=10
a+(c+1/2)+c=10
a+2c+1/2=10
a+2c=9.5
