To find length and width, you use the distance formula: [latex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/latex] For the length, you use the points [latex](-2, 3)[/latex] and [latex](1, 5)[/latex] [latex]d=\sqrt{(1-(-2))^{2}+(5-3)^{2}}[/latex] [latex]=\sqrt{3^{2}+2^{2}}[/latex] [latex]=\sqrt{9+4}[/latex] [latex]=\sqrt{13}[/latex] For the width, you use the points [latex](-2, 3)[/latex] and [latex](2, -3)[/latex] [latex]d=\sqrt{(2-(-2))^{2}+(-3-3)^{2}}[/latex] [latex]=\sqrt{4^{2}+(-6)^{2}}[/latex] [latex]=\sqrt{16+36}[/latex] [latex]=\sqrt{52}[/latex] [latex]=2\sqrt{13}[/latex] So we multiply: [latex]\sqrt{13}*2\sqrt{13}=2*13=26[/latex] which is the area.

you only need multiple for the perimeter
