El area de un rombo es de 45 cm2 , si una de sus diagonales mide 7.2 cm determina el valor de la segunda diagonal
angiemontenegrTenemos. Area del rombo = diagonal mayor * diagonal menor /2 A = D * d/2 45cm² = 7,2cm * D/2 45cm² * 2 = 7,2cm* D 90cm²/7,2cm = D 12,5cm = D
Area del rombo = diagonal mayor * diagonal menor /2
A = D * d/2
45cm² = 7,2cm * D/2
45cm² * 2 = 7,2cm* D
90cm²/7,2cm = D
12,5cm = D
La diagonal mayor del rombo es de 12,5cm
