Answer:

Option A [tex]P=26\ in[/tex]

Step-by-step explanation:

we know that

The perimeter of the rectangle is equal to

[tex]P=2(L+W)[/tex]

we have

[tex]L=10\ in[/tex]

[tex]W=L-7[/tex] -----> equation A

substitute the value of L in the equation A

[tex]W=10-7=3\ in[/tex]

Find the perimeter

[tex]P=2(10+3)=26\ in[/tex]
