Give an explanation to go with your answer! a rectangle is placed symmetrically inside a square. the rectangle has sides of length m and n. find the area of the square in terms of m and n.

Step-by-step explanation:

Look at the picture.

We have the triangles 45° - 45° - 90°. The sides are in ratio 1 : 1 : √2

(look at the second picture).

Therefore we have the equations:

 and  

Solve:

               multiply both sides by √2

              divide both sides by 2

               multiply both sides by √2

            divide both sides by 2

The side length of square is

The area of a square:

Okay so n is going to represent our first number. since the second number of five times greater than n, the second number will be represented as 5n. for us to figure out the two  numbers we need to have  the value of n first. this is going to be done by adding the two numbers together, n and 5n. it can be simplified as 6n, which the problem states is equal to 72. divide 72 by 6n and you can solve for n.  n+5n=726n=72n=(72/6)n=12  now that we know the value of n, we have to multiply 5 times 12 which equals 60. so our two numbers/integers are 12 and 60
