Answer:
3.18, 3.21, 3.23
Step-by-step explanation:
You just nee to find some decimals that round up to 3.2
length = 15
let the width = w then length = 2w - 3
Perimeter = 2(length + width)
= 2(2w - 3 + w) = 2( 3w - 3) = 6w - 6 = 48
hence 6w = 48 + 6 = 54 ⇒ w == 9
Thus length = 2w - 3 = (2× 9) - 3 = 18 - 3 = 15

5 3/4 - 2 1/2
3 1/4 - 2/3
24/ 7 - 8/7
16/7
simplified it is 2 1/3
