Answer:
480 cm²
Step-by-step explanation:
New side lengths:
80% of 30 cm = 0.8% × 30 cm = 24 cm
80% of 25 cm = 0.8 × 25 cm = 20 cm
area = length × width
area = 24 cm × 20 cm
area = 480 cm²
Vertex=(0,0)
directrix is x=2.5
or x-2.5=0
so focus S is (-2.5,0)
let P(x,y)be any point on the parabola.
Let M be the foot of perpendicular from P(x,y) on the directrix.
then SP=PM
