@surjithayer plz help

it asks for the perimeter of the triangle.

5. Spring98

yes and i counted out 12 but there is no 12 on the answer choices

6. anonymous

since it's a right triangle you know that to get the hypotenuse its going to be $c = \sqrt{a^2+b^2}$ then you'll just add the straight line distances

or you could say $P = A + B + \sqrt{A^2+B^2}$ where A and B are the straight lines

@surjithayer plz help

$P = 4 + 4 + \sqrt{4^2 + 4^2}$

perimeter=4+4+4*1.414=8+5.656=13.656=14 approx

12. anonymous

13.656 round it up and it's 14

13. Spring98
