Question 757459
The perimeter is just the length of all sides added up.

In this case you said two sides were 5" and the last side was 6".

Adding them all up you get 5" + 5" + 6" = 16"

The area of the triangle is found by multiplying base times height then dividing by 2.

{{{A = (1/2)*b*h}}}
{{{A = (1/2)*6*4}}}
{{{A = 12}}}
