How do you solve number 29?

Step-by-step explanation:
Now, I will explain using both area and perimeter.
[tex]6.25 + 5 + 6.25 + 5[/tex]
[tex]6.25 + 5 = 11.25[/tex]
Now we can infer that the other 6.25 +5 will have the same sum. Therefore we have to solve this:
[tex]11.25 + 11.25[/tex]
Which is:
[tex]11.25 + 11.25 = 22.50[/tex]
Now time to solve in the area formula.
[tex]l \times w[/tex]
Length × Width.
First, we're starting by 6.25 × 5.
Which is 62.5.
Either, he had to pay 62.5$ (I doubt it) or he had to pay 22.50$.

I have solved using both formulas, hope this helps, bye!
