Question

What is the perimeter of the isosceles triangle shown below? If necessary, round to the nearest hundredth. A. 27 units B. 32 units C. 22units D. 24 units

Answer 1

The perimeter of the isosceles triangle will be option ''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 a new point of 90 degrees. This is found at the 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.
