An equilateral triangle has a perimeter of 48 centimeters. if the triangle is dilated by a factor of 0.75, what is the length of each side of the new triangle?

The length of each side is 28 cm. 
the perimeter of the equilateral triangle is 48 cm. To find each side of the original triangle, you do 48/3=16cm. since the triangle dilate by 0.75, then you can just do 0.75*16=12cm. then you have to add 12 to 16 because the triangle gets bigger by 12 cm. so 16+12=28 cm.
