The width of the rectangles is 4.
Explanation:
Given that two rectangles have same width. So, let be the two rectangles
and
and width of rectangle is ‘x’. So, according to question, we have
Length of one rectangle ,
= x + 1
Length of other rectangle,
= x + 2
But we also know that,

So, then the area for one rectangle,

Similarly,

So, according to question,


Now, by solving the above equation, we get


So, from the above equation, we found that width of the rectangle is 4.
