b. h = 2(480)
b² + h² = 52²
por producto notable:
(b + h)² = b² + h² + 2(b.h)
= 52² + 4(480)
= 4²13² + 4²(120)
= 4² (169 + 120)
= 4². 17²
b + h = 4.17 = 68
entonces:
(b + h)² - (b - h)² = 4b.h
68² - (b -h)² = 4(960)
68² - 8(480) = (b - h)²
4².7² = (b - h)²
28 = b - h
entonces por sistema de ecuaciones:
b - h = 28
b + h = 68
rpta. b = 48 y h = 20
