Question

Write a dimension of a rectangle that is similar to a rectangle that measures 4.2 units by 6.8 units.

a) 4.2 units by 6.8 units
b) 2.1 units by 3.4 units
c) 8.4 units by 13.6 units
d) 2.7 units by 4.4 units

Answer 1

To find a dimension of a rectangle that is similar to a given rectangle, we need to find a dimension that maintains the same ratio between length and width.

Step-by-step explanation:

To find a dimension of a rectangle that is similar to a rectangle that measures 4.2 units by 6.8 units, we need to find a dimension that maintains the same ratio between length and width. The scale factors between the two rectangles are:

Length scale factor = 4.2 / 2.1 = 2

Width scale factor = 6.8 / 3.4 = 2

Therefore, the correct answer would be b) 2.1 units by 3.4 units as it maintains the same ratio as the original rectangle.
