Perimeter=$2+2\sqrt2$ inches Area=$1$ square inch
Perimeter is the sum of the lengths of the sides. $P=2+\sqrt2+\sqrt2$ Combine like radicals. $P=2+2\sqrt2$ The area of a triangle is one half the product of the base and height. $A=\frac{1}{2}bh$ $A=\frac{1}{2}(\sqrt2)(\sqrt2)$ Use the product rule for square roots. $A=\frac{1}{2}\times2$ Simplify. $A=1$
