El perimetro de un rectangulo es de 56m. la base representa el triple de la altura . ¿ cuanto mide c.... Question from @mirtagenes

profeplease X=altura. 3x= base

x+(3x)+x+(3x)=56. 8x=56. x=56/8. x=7. altura=7. base=3x= 3.7= 21m

área= ( base.altura)/2. despejo la base. base=(2.área)/altura. base= (2.72)/8=18cm

Haiku El perímetro de un rectángulo cuya medida de sus lados son a,b es dos veces a, más dos veces b.

P = 2a+2b
Si a = 3b
P = 2*3b+2b = 6b+2b = 8b
8b = 56
b = 56÷8
b = 7 m
a = 3*b = 3*7 = 21

Solución:
Los lados del rectángulo miden 7m y 21m

El área del triángulo es base x altura dividido entre 2

A = 72 cm²

$A= \frac{b*h}{2}$

$72= \frac{b*8}{2}$

8b = 144
b = 144÷8
b = 18 cm

Solución: 18 cm
