Question 296780
{{{a^2+b^2=c^2}}} a=40 b=42 c=hypotnuse
use above equation to solve for "c"
{{{highlight(c=58)}}}
{{{a+b+c=P}}} p= perimeter
once u have found "c" use above equation to find the perimeter.
{{{highlight(P=140)}}}
{{{(1/2)bh=A}}} A= Area of triangle b=base h=hieght
b=40 and h=42 use the above equation to find the area
{{{highlight(840)}}}

you should be able to do the work as im not going to do ur homework since u posted the question from ur assignment. if u come out with the same answers then you did the work corectly. dont forget the units.
