3/2.5 = 48/c
Cross multiply
3*c = 3c
2.5 * 48 = 120
3c = 120
3c/3 = 120/3
c= 120/3
c= 40
Answer: c = 40

Answer:
tienes que sumar dos veces 2370 y despues dividirlo
Let's say that BC is x, so that AB is 4x, and AE = y.
The shaded area then is represented by 4xy/2 = 2xy.
The total area is represented by (4x+x)*y = 5xy.
The fraction of these is 2xy/5xy = 2/5.
