The ratio of the corresponding side lengths of two similar posters is 7 in:20 in. What is the ratio of the perimeters?

gregori [183]

The ratio of their perimeters is still 7:20. The poster is a rectangle shape. If the length of each side of a poster is proportional to the other by a certain ratio, the sum of the lengths of all sides is also proportional by the same ratio. You can suppose the lengths of four sides of poster A are 7a, 7b, 7c, 7d, so poster B has 20a, 20b, 20c, 20d. (7a+7b+7c+7d)/(20a+20b+20c+20d)=7(a+b+c+d)/20(a+b+c+d)=7/20.

What is the value of b? −7.5(x−3)=3.75

KengaRu [80]

I am assuming x is the same thing as b.
−7.5(x−3)=3.75
-7.5x+22.5=3.75
-7.5x=-18.75
x=2.5
