$5\dfrac{1}{2}\ inches$

Step-by-step explanation:

The perimeter of the rectangle is

$P=2(\text{Length}+\text{Width})$

From the diagram,

Length = $1 \frac{1}{2}$ inches

Width = $1\frac{1}{4}$ inches

So, the perimeter is

$P=2\left(1\dfrac{1}{2}+1\dfrac{1}{2}\right)$

Add numbers in brackets:

$1+1=2\\ \\\dfrac{1}{2}+\dfrac{1}{4}=\dfrac{2}{4}+\dfrac{1}{4}=\dfrac{3}{4}\\ \\1\dfrac{1}{2}+1\dfrac{1}{4}=\dfrac{8}{4}+\dfrac{3}{4}=\dfrac{11}{4}$

Now, multiply it by 2:

$P=2\cdot \dfrac{11}{4}=\dfrac{11}{2}=5\dfrac{1}{2}\ inches$
