Answer: 8,100 cm^2
Step-by-step explanation: Area = S^2 so each side is sqrt(900) = 30cm
A square 3 times bigger has sides 30cm*3 = 90cm. The area for that square is 90^2 = 8,100 cm^2
TRUE
To visualize this property, you can draw two parallel lines and cross them by a third line.
Corresponding angles are those that are in the same relative position, between the crossing line and the parallel lines. You can see that those (corresponding) angles are equal if and only if the lines are parallel.
