Rectangle !!
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.
Find the original lenth and width

Re: Rectangle !!
Furthermore...
1) How many solutions to this problem are there?
2) What would the dimensions of a square with the above property be?

Re: Rectangle !!
Why did the vector cross the road?
It wanted to be normal.

Re: Rectangle !!
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 !!

should the original rectangle be a square, or the after the width and height have been increased?

Ah, good question... how about both, just for the practice!
(not at the same time though - two separate questions 
)

Re: Rectangle !!
if you let the original rectangle be a square:
if you let the result be a square:
