PLEASE ANSWER BOTH 1) A rectangle has a perimeter of 50 centimeters. If the width of the rectangle is 10 centimeters, what is its length?

a 5 centimeters

b 15 centimeters

c 20 centimeters

d 40 centimeters

2) Makela is putting up a fence in her yard to make a dog run. The dog run is 20 feet long and 15 feet wide. How much fencing does she need for the dog run?

a 35 feet

b 55 feet

c 70 feet

d 300 feet

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
