Question

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.

Answer 1

4 * 1.5 = 6 cm <==

Explanation:

Answer 2

first we find the scale factor. It went from a 11 cm length to 16.5 cm length....so 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 <==
