Gabriella wants to tile a room with an area of 320 square feet. The width of the room is 4/5 its length. What are the length and width of the room?
Answered by Steve
length=x, so width = 4/5 x

(x)(4/5 x) = 320
4x^2 = 1600
x^2 = 400
x = 20
width=4/5 x = 16

check:

16*20 = 320

I’m doing a problem it says “ Isabel wants to estimate the length, width and height of her bedroom. If her bedroom was empty, the volume of her room would be 864 cubic meters. Her bedroom’s length are the same measurements but the height is half the length and width. What are the dimensions of Isabel’s bedroom?”
