The red figure is smaller so it is a reduction.
To find the scale factor divide the length of the smaller shape by the length of the larger shape:
9/15 this can be reduced to 3/5
You have 28 meters of fence to make 3 sides.
28/3 = 9.3333
The pen will be 9.3333 by 9.3333 meters
Answer:
25
Step-by-step explanation:
because there are vertical angles
We known that the figures are similar if and only if the corresponding sides and and angles have the common scale factor. In this item, the scale factor is 0.6. The length of AB is determined by multiplying the length of FG with the scale factor. That is,
AB = FG x scale factor
AB = (12 cm) x 0.6
AB = 7.2 cm
Thus, the length of side AB is 7.2 cm.
