Answer:
x²/9 − (y + 1)²/81 = 1
Step-by-step explanation:
-2y − 82 + 9x² = y²
9x² = y² + 2y + 82
9x² = y² + 2y + 1 + 81
9x² = (y + 1)² + 81
9x² − (y + 1)² = 81
x²/9 − (y + 1)²/81 = 1
The product of side length and altitude is area. The area remains the same regardless of how you measure it.
From the first side and altitude,
.. area = side*altitude = (4.2 cm)*(3.6 cm) = 15.12 cm^2
From the second side and altitude
.. area = side*altitude
.. 15.12 cm^2 = side*(2.4 cm)
.. side = (15.12 cm^2)/(2.4 cm) = 6.3 cm
The perimeter is the sum of the measures of all sides. Opposite sides are of equal measure.
.. perimeter = 2*(4.2 cm +6.3 cm) = 21.0 cm
