Question

the width of Jana's rectangular classroom is 1 meter more then 1/4 of its length. if the perimeter of the classroom is 24 meters what is the length?

Answer 1

Basically multiply 1 x 1/4 then whatever you get divide it

Answer 2

Let's call the length L, the width w.
We have w=1+L/4.
The perimeter is P=2(L+w)=24 hence L+w=12
L+w=L+(1+L/4)=5L/4+1=12
Hence L=11/5*4=8.8 meters
