The length of a rectangle is 3 meters more than the width. the perimeter of the rectangle is 26 meters. if the width is b. which equation represents the situation? how many solutions will this equation have?
a. (b + 3)(b) = 26, which has one solution
b 2(b + 3) + 2b = 26, which has infinitely many solutions
c. 2[(b + 3) + b] = 26, which has one solution
d[(b + 3) + b] = 26, which has no solution

![2l+2b=P\\\\\Rightarrow 2(b+3)+2b=26\\\\\Rightarrow 2[(b+3)+b]=26~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)](/tpl/images/0301/5688/358ce.png)
![2[(b+3)+b]=26\\\\\Rightarrow 2(2b+3)=26\\\\\Rightarrow 2b+3=\dfrac{26}{2}\\\\\Rightarrow 2b+3=13\\\\\Rightarrow 2b=13-3\\\\\Rightarrow 2b=10\\\\\Rightarrow b=\dfrac{10}{2}\\\\\Rightarrow b=5.](/tpl/images/0301/5688/12039.png)
![2[(b+3)+b]=26.](/tpl/images/0301/5688/31788.png)
and the equation has only one solution.
