Answer 1

Jason reasoning is incorrect

Jason should have calculated the perimeter of the room instead of calculating the area

Explanation:

we know that

The perimeter of the rectangular bedroom is equal to

`P=2(L+W)`

where

`L=12\ ft\\W=14\ ft`

substitute

`P=2(12+14)`

`P=52\ ft`

we have that

`52\ ft < 75\ ft`

so

Jason has enough border for the whole job

therefore

Jason reasoning is incorrect

Jason should have calculated the perimeter of the room instead of calculating the area
