Question

A rooms floor is y meters long. It’s width is 5 meters shorter. If the perimeter of the floor is (4y + 1) meters, can you solve for its length?

Answer 1

we know that

shape of room is always rectangle

length = y meters

width =y-5 meters

now, we can find perimeter

perimeter=2*length +2*width

we can plug values

`P=2y+2(y-5)`

now, we are given

this perimeter is 4y+1

so, we can set it equal to 4y+1

`4y+1=2y+2(y-5)`

now, we can solve for y

`4y+1=4y-10`

we can subtract both sides by 4y

`4y+1-4y=4y-4y-10`

`1=-10`

we know that 1 can not be equal to 10

so, we can not solve for y by this information

so, this is impossible o find length with this information...........Answer
