Question 212325
Let x=side length of the square=width of the rectangle
Then x+5=length of the rectangle
---
The area of the square is x(x)
The area of the rectangle is x(x+5)
---
We have the equation:
x(x)+x(x+5)=133
x(x+x+5)=133
x(2x+5)=133
---
But, 133=7(19) its only factors
Coincidentally, if x=7, 2x+5=2(7)+5=14+5=19
---
So x=<u>7 m</u>
