Question

4. Two sides of a parallelogram are 20 cm and 25 cm. If the
altitude corresponding to the sides of length 25 cm is 10 cm,
find the altitude corresponding to the other pair of sides.​

Answer 1

Step-by-step explanation:

altitude of corresponding side (h) = 12.5 CM

let one side (a) = 20cm

corresponding altitude = h cm

second side (b) = 25cm

corresponding side = (h) = 10cm

area of parallelogram

b * corresponding altitude

a * h = b * h

20 * h = 25 * 10

h = 25/2

h = 12.5 CM

altitude of corresponding side (h) = 12.5 cm
