Question

PLS HELP
The perimeter of the rectangle below is 162 ft.
T= ft.

Answer 1

It’s 108t because if you combine like terms then multiple then you get 108t :)

Answer 2

we are given

length =l=7t+1

width =w=5t+8

now, we can use

perimeter of rectangle formula

`perimeter=2(l+w)`

we can plug l and w

`perimeter=2(7t+1+5t+8)`

now, we are given

perimeter=162

so, we can set it equal

`162=2(7t+1+5t+8)`

now, we can solve for t

`162=2(12t+9)`

we can isolate t on anyone side

`162=2*12t+2*9`

`162=24t+18`

`24t=144`

`t=6`

so,

`t=6ft`...............Answer
