blue rectangular tile and red rectangular tile are similar. the blue tile has a length of 10 inches and a perimeter of 30 inches.the red tile has a length of 6 inches. whats is the perimeter of the red tile?
First you must find the height of the blue rectangle by doing 30-20=10 and taking 10/2 =5in height.
Then take a proportion of 5/10= x/6 to find the height of the red rectangle and x=3.
Now that you have the height of the red just plug it in and solve for perimeter.
P= 18in for the red.
