Two sides of a parallelogram are 20 cm and 25 cm. If corresponding altitude to side 25 cm is 10 cm, the altitude corresponding to the other side is?
Answer & explanation
Correct answer: option 4
Area of parallelogram = base × height
⇒ 25 × 10 = 20 × \(x\)
⇒ 250 = 20 × \(x\)
⇒ \(x\) = \(\frac{250}{20}\) = 12.5 cm
