The width of a rectangle is St-7.5 feet and the length is 7.5t +9 feet. Find the perimeter of therectangleThe perimeter of the rectangle is feet.(Simplify your answer. Use integers or decimals for any numbers in the expression)

Respuesta :

The expression of the width is

[tex]8t-7.5[/tex]

The expression of the length is

[tex]7.5t+9[/tex]

The perimeter formula is

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

Let's replace the given expressions

[tex]P=2(8t-7.5+7.5t+9)[/tex]

Now, we have to reduce like terms

[tex]P=2(15.5t+1.5)[/tex]

Then, we use the distributive property

[tex]P=31t+3[/tex]

Hence, the perimeter of the rectangle is 31t+3 feet.
