Question

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)

Answer 1

The expression of the width is

`8t-7.5`

The expression of the length is

`7.5t+9`

The perimeter formula is

`P=2(w+l)`

Let's replace the given expressions

`P=2(8t-7.5+7.5t+9)`

Now, we have to reduce like terms

`P=2(15.5t+1.5)`

Then, we use the distributive property

`P=31t+3`

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