A star plot visualizes an observation XX with nn attributes. If we define the vector V=(v1,v2,,vn)V = (v_1, v_2, \dots, v_n) and the area is calculated as A=12i=1nvivi+1sin(2πn)A = \frac{1}{2} \sum_{i=1}^{n} v_i v_{i+1} \sin(\frac{2\pi}{n}), how does the area change if all components viv_i are scaled by a factor k>1k > 1?
