Kamal’s bedroom has an area of 120 square feet. the width of the room is 5/6 the length of the room. what are the dimensions of kamal’s bedroom?

Let
x> the length of the room
y> the width of the room

we know that
x*y=120> equation 1
y=(5/6)x> equation 2

substitute 2 in 1
x*[(5/6)x]=120> (5/6)x²=120> x²=120*6/5> x²=144
x=12 ft
y=(5/6)*12> y=10 ft

the answer is
the dimensions of Kamal’s bedroom are
the length of the room is 12 ft
the width  of the room is 10 ft

It will be a whole number.
