Answer:
Length = 90 inch.
width = 30 inch
Let width of the rectangle = x inch.
So the length = 3x inch.
Perimeter = 2(length + width) = 2 (3x + x) = 8x.
So,
length = 3x = 3(30) = 90 inch.
width = x = 30 inch
70 laps in 40 hours
1/2+1/2=4
35+35=70
I think
1 1/4x = 3/4
5/4x = 3/4
x = (3/4) / (5/4)
x = 3/4 * 4/5
x = 12/20 which reduces to 3/5
check..
1 1/4 * 3/5 =
5/4 * 3/5 =
15/20 reduces to 3/4
so u would multiply 1 1/4 by 3/5 to get 3/4
The first is 6.13 and the second is 6.28
