since perpendicular is dividing the base into 2 equal parts.so this is an isosceles triangle.

OpenStudy (ledah):

I was thinking it was isosceles.... but Then again the eyes can be decieving

OpenStudy (maheshmeghwal9):

Now, take half the triangle|dw:1337535924428:dw| & use pythagorus to get another side which comes out to be 17

OpenStudy (maheshmeghwal9):

now, perimeter is 17+17+16=50 units
