If the 3 numbers are in the ratio of 1:3:5, then all together,
they make (1 + 3 + 5) = 9 parts.
Since 72 has been split up into 9 parts, each part is (72 / 9) = 8 .
So the numbers are
1 part . . . . 1 x 8 = <em>8</em>
3 parts . . . 3 x 8 = <em>24</em>
5 parts . . . 5 x 8 = <em>40</em>
<u>Check:</u>
8 / 8 = 1
24/8 = 3
40/8 = 5
8 + 24 + 40 = 72 yay !

Answer:
12inches
Step-by-step explanation:
12x3=36 triangle perimeter
8x4=32 square perimeter
Numbers below 0 and that have the - before it for example -1, -2, -3
500•1.1= 550, 320•1.1= 352, 80•1.15= 92, 75•1.25= 93.75
