Plz this is due tommorow and i am stuck if the perimeter of a rectangle is 78 cm, and its length equals 3+2(width) what is an equation to find the width and length

since perimeter is the total of the length plus length plus width plus width:

L+L+W+W= 78 cm (given in the problem) as the total perimeter; and remember the length (we are told in the problem) is equal to 2 times width. so:

3 +2w+3+2w=78

6 +4w=78

6+4w-6=78-6

4w=72

w=18

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
