5x = length
4x = width
324 = perimeter
formula: P = 2(length) + 2(width)
324 = 2(5x) + 2(4x)
324 = 10x + 8x
324 = 18x
18 = x
Substitute the value of x = 18
Length = 5x = 5(18) = 90meters
Width = 4x = 4(18) = 72meters
1 7/9-2/9=1 5/9
Hope this helps:)
153 000 = 100 000 + 50 000 + 3 000
Well 41 divided by 6 is 6.8333333333333 so you just need to subtract .833333333333
