In the above diagram, ADFE is a square and ABCD is a rectangle. The perimeter of ABCD is 132 and
EB :AB =3:7.
Find the length of AE
Find the ratio of the area of rectangle EBCF to the area of rectangle ABCD is simplest form.

Your help is will be greatly appreciated!!!!
 
I'm not sure that I understand your last reply; you do not know how to begin thinking? That is, you have no thoughts whatsoever about this exercise?

There are different ways to solve this exercise.

One method is to set up and solve a system of two equations involving two variables.

Have you learned yet how to solve a system of two equations?

EG:

4x + 2y = 132

y/(x + y) = 3/7

If you cannot solve this system, then I will need to guess again. :cool:

I assume your picture that the three line segments AD, EF, and BC The same length. Let's call that "x", and call the length of AE "y" and the length of DB "z". Do you know how to find the perimeter of the two rectangles in terms of x, y, and z? What about the areas of the two rectangles? Do you understand what "EB:AB= 3:7" means?
