The area of a scale model of the Central Park ice-skating rink has an area of 16 square inches. The area of the actual ice skating rink in Central Park has an area of 400 square inches. What scale factor was applied to the scale model to get to the actual rink?

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

The answer would be 7 cages

  the product is divided by 2, and then 5 is added.
