Explicación paso a paso:
pQ = √ (x2-x1)²+ (y2-y1)² = √ (2-4)²+(1-7)²
√ 4 + 36= √ 40= -6,32cm
QR = √(3-2)²+(-3-1)² = √ 2+(-16 = √ -14 = -3,74
RS = √ (-3-3)²+(-5+3)²= √ -36+(-4) = √ 40 = -6,32cm
ST = √(-1+3)²+(-2+5)²= √ 4+9= √ 13 = 3,60cm
TU= √(-6+1)²+(-2+2)²= √-25+0 = -5cm
UP = √ (4+6)²+(7+2)² = √ 100+81= √181 = 13 ,43
p = 6,32cm+ 3,74cm + 6,32cm+3,60cm+5cm+13,43cm
perímetro = 38,41 cm
