Answer:
The constant of proportionality is 5.
Step-by-step explanation:
If the quantity q varies inversely with the square of m and directly with the product of r and x, then the variation equation is

When q=2.5, m= 4 and the
product of rx = 8.
We plug in this values to get;



Multiply both sides by 2

The constant of proportionality is 5.

² = QR² - QT²
= 13² - 5²
= 169 - 25
= 144
TR = √144
TR = 12 cm
Menentukan panjang PR
PR = 2 × TR
= 2 × 12 cm
PR = 24 cm
