Answer:

Perimeter of one of the triangle=
17.071 inch

Explanation:

The triangle has:

$Perpendicular= 5 inch\\Base = 5 inch \\Diagonal(Hypotenuse)=?$

Using the Pythagorean Theorem;

$( Hypotenuse)^2=(Perpendicular)^2+(Base)^2\\H^2= 5^2+5^2\\H^2=25+25\\H^2=50\\$

$H=√(50)\\or\\H=7.071 inches$

The Perimeter of one of the triangle is =

$Perpendicular+Base+Hypotenuse\\5+5+7.071\\17.071inch$

This is equal for the other triangle.
