Answer:
0.01785714285
Step-by-step explanation:
You can round it to 0.18 or something but yeah
First convert feet to inches:
18 ft × (12in/1ft)= 216 in
15 ft × (12 in/1ft)= 180 in
divide each side of the room by 9 inches to get number of white tiles per a wall
wall 1(18ft): 216in/9in= 24 white tiles
wall 2(15ft): 180in/9in= 20 white tiles
wall 3(18ft): 216in/9in= 24 white tiles
wall 4(15ft): 180in/9in= 20 white tiles
Lastly, add up all the white tiles and subtract 4 (the tiles that we counted twice because they were the corner tiles and touched both walls)
24+20+24+20-4= 84 white tiles total
Answer:
Width = 10 and Length = 16
Step-by-step explanation:
→ Assign variables to the length and width
width = x so length = 6 + x
→ Make an equation
x + 6 + x + x + 6 + x = 52
→ Simplify
4x + 12 = 52
→ Minus 12 from both sides
4x = 40
→ Divide both sides by 10
x = 10
→ Resubstitute into the previously assigned values
width = 10 so length = 16
