Question

Gabby wants to tile a room with and area of 320 Square feet. The width of the room is 4/5 it's length. What are the length and width of the room

Answer 1

lenght - a
width - b
Area= a*b
320=ab
b=4/5a
320= 4a^{2}/5
400= a^{2}
a= \sqrt{400}
a=20
b=16

Answer 2

I hope this helps you



width=4/5.length



width×length =320


4/5.length ×length =320


length ^2=400


length =20


width =16
