# please help me you get 24 points I forgot how to find the area of a rectangle I know its l*w but I don't remember how to it. please help and explain step by step.

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