The perimeter of a rectangle can be found using the expression 2l+2w where l represents length and w represents width. find the perimeter if = 6 units and w= 3 units.

18 units

Step-by-step explanation:

Let's write out that perimeter formula:  P = 2L + 2W.

Substitute 6 for L and 3 for W:               P = 2(6) + 2(3) = 18 units.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
