The length of a rectangle was increased by 10 m , the width was increased by 5m ,

as a result the area was increased by 1050 m².

Furthermore...

1) How many solutions to this problem are there?

2) What would the dimensions of a square with the above property be?

Why did the vector cross the road?

This is a question found in a " pre calculus " book , the authers put 80 m and 60 m as the answers , i could reach one equation in two variables , but never come to a second equation .

Now , if we know that the answer should be 60 m and 80 m , can we work back to find any new equation !!

thanks Dross
