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.

Answer:
Step-by-step explanation:
Important information:
Circumference of a circle= 
Method:
To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.
Step By Step:
1) Rearange the formula to make the diameter the subject.
2) Divide 34.54 by 3.14(
).
It is always isosceles because it can be proved as follows:
The perpendicular bisector dissects the triangle into two, and it is the common side. Then each side of the bisector is 90 degrees, and the bisected to two equal sides, so the two dissected triangles are congruent, hence the original triangle is isosceles.
There is only one solution since x=0 x cant be many things since the only thing that would make this true is 0
