Susan enlarged to scale a rectangle with a height of 4 cm and length of 11 cm on her computer. the length of the new rectangle is 16.5 cm. find the height of the new rectangle.

First we find the scale factor. It went from a 11 cm length to 16.5 cm lengthso we have to find out what to multiply 11 by to get 16.5.
11x = 16.5
x = 16.5 / 11
x = 1.5
and since we multiplied 11 * 1.5 = 16.5, then we have a scale factor of 1.5...so we now multiply the height of 4 by 1.5.
So the new height is gonna be : 4 * 1.5 = 6 cm <==
