Answer:
D. 32 units
Step-by-step explanation:
Isosceles measures 11 + 11 + 10 base.
Area = 32 unit sq
We can double check by creating a vortex and new point 90 degree. This is found at central height line.
base = 5 square 25 12 square 144 (144-25=√119) = 10.91
As we can prove that the matching sides are 10.91
= 10.91 +10.91 +12 = 32 with rounding (= 11 +11 + 10 = 32).
= 32units.
