Answer: 30 inches.

Step-by-step explanation:

We need to use the formula for calculate the perimeter of a rectangle. This is:

[tex]P=2l+2w[/tex]

Where "l" is the length and "w" is the width.

In this case, we know that the lenght and the width of this rectangle are:

[tex]l=8\ in\\\\w=7\ in[/tex]

Therefore, substituting values into the formula, we get that the perimeter of this rectangle is:

[tex]P=2(8\ in)+2(7\ in)\\\\P=30\ in[/tex]

For this case we have to by definition, the perimeter of a rectangle is given by:

[tex]P = 2a + 2b[/tex]

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

We have as data that:

[tex]a = 8 \ in\\b = 7 \ in[/tex]

Substituting the data:

[tex]P = 2 (8) +2 (7)\\P = 16 + 14\\P = 30[/tex]

Finally, the perimeter of the rectangle is[tex]30 \ in[/tex]

ANswer:

[tex]30 \ in[/tex]
