Arectangular picture has dimensions 2½ by 1½. it is to be enlarged so that it is still similar to the original rectangle. if the longer dimension is now 10, how much longer than the original is the perimeter now

Original Perimeter = 2.5 + 2.5 + 1.5 + 1.5 = 8
The longer dimension is 2.5 as 2.5 > 1.5To make 2.5 into 10, we must multiply by 4For the smaller length, we must also multiply by 41.5 x 4 = 6
New Perimeter = 10 + 10 + 6 + 6 = 32
Now find the difference between the old and the new perimeter32 - 8 = 24
